Merge feature/main-window-shell into dev

M3-b — Main Window shell (2a): the exploration HUD frame every screen lives in. Two-panel tabletop split — dark world slot (turn rail, minimap, slide-in system dock, command bar) + the permanent DM narration book wired to the proven /dm/narrate loop (prose-only + refire, considering-state, fallback, fact-harvest). Thin tested ShellState; suite 138/138. Establishes the editor-first UI-scene convention (ADR 0001): screens are authored as .tscn node trees, scripts do on-load work only. Theme gained Button-base DockButton/ParchmentButton + a base RichTextLabel prose style.

+## UI scene conventions (shell + all screens)
+
+Screens are **authored editor-first** — the layout lives in the `.tscn`, not in
+code. See ADR [0001](../../docs/adr/0001-editor-first-ui-scenes.md) for the why;
+this is the how. Reference: `scenes/shell/{MainWindowShell,SystemDock,NarrationBook}.tscn`
+ `scripts/ui/shell/*.gd`.
+
+- **The `.tscn` owns the tree.** Author every node in the editor: containers,
+  panels, labels, buttons, art-slot placeholders. Assign the shared theme on the
+  scene root (`theme = game_theme.tres`) and set each node's `theme_type_variation`
+  (from `ThemeKeys`) in the editor, so the scene previews themed. Instance
+  sub-screens (`PackedScene` ext_resource) rather than rebuilding them.
+- **The script does on-load work only.** `@onready var x := $Path/To/Node` refs,
+  signal/service wiring, animations, and binding state into the authored nodes
+  (label text, colours from `Palette`). Do **not** create nodes in `_ready()`.
+- **Data-driven repeats = fixed authored slots, bound at runtime.** Author enough
+  turn-order tokens / consumable slots / etc. in the editor; the script fills the
+  first N from state and hides the rest. Previewable now; systems write them later.
+- **Scene-root sizing.** Give the root a fixed size via offsets (e.g. 1920×1080)
+  for editor preview, but **no full-rect anchors on the root** — a root Control run
+  via F6 collapses to (0,0) under full-rect anchors. Keep `size = get_viewport_rect().size`
+  on `_ready` + a `size_changed` connection (the M3-a collapse lesson).
+- **Button styling → Button-base variations only.** Never put a PanelContainer
+  variation (`DarkPanel`, `ParchmentCard`) on a `Button`; it has no `normal/hover/
+  pressed` styleboxes so the button renders unskinned. Use the Button-base
+  variations (`PrimaryCTA`, `Tab`, `TabActive`, `Chip`, `DockButton`, `ParchmentButton`).
+- **`RichTextLabel` prose** reads its dark serif ink from the theme's base
+  `RichTextLabel` style (it does *not* inherit `default_font`/`default_color`).
+  Just add the `RichTextLabel` — don't override its colour per-node.
+- **Theme is generated.** All colours live in `palette.gd`; `game_theme.tres` is
+  built by `scripts/theme/build_game_theme.gd` (source of truth). To add/adjust a
+  variation, edit the builder + `theme_keys.gd`, then regenerate:
+  `godot --headless -s res://scripts/theme/build_game_theme.gd`. Never hand-edit
+  the `.tres` or put a hex literal in a script or `.tscn`.
+- **Wiring the DM loop / injectable services.** Follow the shell: a `service`
+  var settable *between* `instantiate()` and `add_child()` lets tests inject a
+  `FakeTransport`-backed `DmService` so on-load calls stay hermetic; `_ready`
+  builds the real `HttpTransport`-backed one when none was injected.
+- **Visual gate.** Headless GUT proves structure (nodes mount, sizes non-zero,
+  bindings run); it cannot prove rendering. Every screen needs a **human F6
+  eyeball** before it's done. Note shader surfaces (`DarkBay`, vignette) render
+  their texture only on an F6 run, not in the editor.

+# 0001 — UI screens are editor-authored scenes, not code-built
+
+- **Status:** accepted
+- **Date:** 2026-07-11 (M3-b, Main Window shell)
+
+## Context
+
+The M3-b Main Window shell was first built by constructing every Control node in
+`_ready()` (a pattern borrowed from `theme_showcase.gd`, where it was fine because
+the showcase is a throwaway proof). For a real screen this was wrong:
+
+- **It does not preview in the Godot editor.** Opening the `.tscn` showed a bare
+  root Control — every widget only existed at runtime — so the human could not see
+  or arrange the layout in the editor. Tuning meant editing pixel offsets in code,
+  running, eyeballing, repeating.
+- It buried layout, styling, and content in GDScript, where it is verbose and
+  hard to reason about, and it drifted from charter §16's own words: *"each screen
+  is recreated as a Godot 4.7 Control-node scene."*
+
+The human asked to be able to arrange the scene in the editor "as much as
+possible," with code only for genuine on-load work.
+
+## Decision
+
+**UI screens (and their sub-scenes) are authored editor-first as `.tscn` node
+trees.** The split:
+
+- **In the `.tscn` (editor):** the whole node tree — containers, panels, labels,
+  buttons, art-slot placeholders — with the shared `Theme` assigned on the scene
+  root and every `theme_type_variation` set on its node. Authored placeholder
+  text/values so the screen previews with representative content. Sub-screens are
+  **instanced** (`ExtResource` PackedScene), not rebuilt.
+- **In the script (on-load only):** `@onready` references to named nodes; wiring
+  (signals, the DM loop, injected services); animations (e.g. the dock slide);
+  and **binding state into the authored nodes** (setting label text/colours from
+  the model). Never construct the tree in `_ready()`.
+- **Data-driven repeats** (turn-order tokens, consumable slots, later inventory
+  grids) are a **fixed set of authored nodes** bound from state at runtime —
+  spare slots hide. This keeps them previewable; combat/inventory become the
+  writers later. (Author enough slots for the common case; if a screen ever needs
+  a genuinely unbounded list, revisit with a code-instanced container then.)
+
+Supporting conventions established alongside this decision:
+
+- **Scene root sizing.** Give the `.tscn` root a fixed size (e.g. 1920×1080) via
+  offsets so it previews, but **no full-rect anchors on the root** — a root
+  Control run via F6 is not sized by full-rect anchors and collapses to (0,0).
+  The script keeps `size = get_viewport_rect().size` on `_ready` +
+  `size_changed` (the M3-a lesson).
+- **Button styling uses Button-base theme variations.** Never apply a
+  PanelContainer-base variation (`DarkPanel`, `ParchmentCard`) to a `Button` — a
+  Button looks up `normal/hover/pressed`, which a `panel`-only variation lacks, so
+  it renders unskinned. M3-b added Button-base `DockButton` and `ParchmentButton`
+  to the theme for exactly this.
+- **RichTextLabel prose reads its style from the theme.** `RichTextLabel` does
+  **not** inherit `default_font`/`default_color`, so without a theme entry its
+  text renders near-white (unreadable on parchment). The theme now sets a base
+  `RichTextLabel` style (dark `INK_BODY` serif + italic face). All colours still
+  come from `Palette` via the theme builder — no hex in scripts or `.tscn`.
+
+## Consequences
+
+**Easier:**
+
+- The human arranges any screen directly in the Godot editor; layout persists in
+  the `.tscn`. Fine-tuning is drag-and-drop, not code-run-eyeball.
+- Screens preview with themed, representative content on open.
+- Scripts shrink to logic; less code, easier to review, focused files.
+- The look stays one system (theme assigned per scene root).
+
+**Caveats / harder:**
+
+- **Shader surfaces render only at runtime.** `DarkBay`/`VignetteOverlay` set
+  their `ShaderMaterial` in `_ready()` (M3-a accepted deviation), so their
+  texture appears only on an F6 run — the editor shows layout but a plain panel
+  behind it. Layout still previews fine.
+- Tests reference nodes by their authored `@onready` paths; renaming/moving a
+  node in the editor means updating the path (and any test that reads it).
+- The visual gate stays a **human F6 eyeball** — headless tests prove structure
+  (nodes mount, sizes are non-zero, bindings run) but not rendering.

+# Main Window shell (2a) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the exploration HUD — a two-panel "tabletop split" frame with an isometric world-view slot, a permanent DM narration book wired to the proven `/dm/narrate` loop (prose-only + refire), a slide-in system dock, and a command bar — over a thin, tested `ShellState`.
+
+**Architecture:** House pattern — pure, tested cores behind thin scene shims (like `DmService`/`ConsideringPhrases`). `ShellState` is a tested value model; `SystemDock`/`NarrationBook`/`MainWindowShell` are Control scenes whose logic seams (signal emission, prose consume, dep injection) are unit-tested and whose layout is eyeball-gated by an F6 run. The narration book is the one live seam; everything else is faithful placeholder.
+
+**Tech Stack:** Godot 4.7, GDScript, GUT (headless). Reuses the M3-a Theme (`game_theme.tres`, `ThemeKeys`, `Palette`, surface scenes) and the M2 DM loop (`DmService`, `HttpTransport`, `FallbackLibrary`, `ConsideringIndicator`, `CanonLog`).
+
+## Global Constraints
+
+- **Godot 4.7 / GDScript.** No C#. Match surrounding style.
+- **`Palette` is the only home for hex colours.** No colour literal may live in any new file — read `Palette.*`.
+- **Theme variations via `ThemeKeys`** — set `theme_type_variation` to a `ThemeKeys` constant, never a raw string.
+- **`§2`: code owns state, AI owns text.** `ShellState` and HUD numbers are state (client-owned); narration prose is text (consumed from `/dm/narrate`, never a source of truth — only harvested `[FACT]` tags become state).
+- **Degrade, never error (§13).** Any non-200 → `DmService` already returns the authored fallback. Add no new failure surface.
+- **Never surface LCK / any Luck number (§7).** Not in the HUD, not in the seed log's rendered fields.
+- **New `class_name` scripts need an import pass before GUT resolves them.** `./run_tests.sh` runs `godot --headless --import` first, so always test through it.
+- **Canvas is 1920×1080.** World panel 1180 wide, narration book 740 wide.
+- **Root-Control viewport-fit gotcha:** a root `Control` run via F6 is not sized by full-rect anchors — it collapses to `(0,0)`. `MainWindowShell` must set `size = get_viewport_rect().size` in `_ready()` and reconnect on `size_changed`. Its `.tscn` root must NOT set `anchors_preset`.

+### Task 5: Visual gate — human F6 run
+
+**This task is not automatable.** Headless GUT cannot prove rendering (the M3-a lesson: a root Control collapsed to 0×0 and every test still passed). A human must eyeball the scene.
+
+- [ ] **Step 1: Open the scene in the Godot editor and run it**
+
+Open `client/scenes/shell/MainWindowShell.tscn`, press **F6**. For the live DM prose, have the proxy + Ollama up (see `client/docs/README.md` live-smoke steps); without them the book must degrade to the authored fallback line (§13), not error.
+
+- [ ] **Step 2: Confirm the checklist by eye**
+
+  - The two-panel split fills 1920×1080 — world on the left (dark stripe + vignette), parchment book on the right. **Not** collapsed / blank.
+  - Turn-order rail (top-left), minimap slot (top-right), command bar (bottom: HP/MP/gold, 8 consumable slots, END TURN).
+  - The gold dock handle slides the dock in/out when clicked; the arrow flips ‹ / ›.
+  - The book shows the header (`ROUND 4 · THE LOWER WARD`), then either live DM prose or the fallback line; the considering line rotates while a call is in flight.
+  - Pressing **▸ The Master continues…** refires narration (or degrades cleanly if the proxy is down).
+
+- [ ] **Step 3: Report the outcome**
+
+If anything is collapsed, mis-coloured (hardcoded hex would show here), or errors, fix and re-run before the branch is considered done. When it looks right, the milestone is eyeball-confirmed and ready to merge to `dev`.

+
+## Self-Review
+
+**Spec coverage:**
+- Iso world slot (art slot) → Task 4 `_build_world` (DarkBay + caption). ✓
+- DM narration book wired to `/dm/narrate` + considering-state → Task 3. ✓
+- Turn-order rail → Task 4 `_build_turn_rail` from `ShellState.turn_order`. ✓
+- Minimap slot → Task 4 (placeholder Panel). ✓
+- Slide-in system dock (6 toggles incl. Spellbook, inert) → Task 2. ✓
+- Command bar (HP/MP/gold, consumables, End Turn) → Task 4 `_build_command_bar`. ✓
+- Thin tested `ShellState` → Task 1. ✓
+- Refire control, prose-only, inert choices/free-text → Task 3. ✓
+- Degrade on non-200 (§13) → reused `DmService`, asserted in Task 3. ✓
+- Fact-harvest (§11) → Task 3 `narrate()`, asserted. ✓
+- Viewport-fit gotcha → Task 4, asserted in test + Task 5 eyeball. ✓
+- Visual gate → Task 5. ✓
+
+**Placeholder scan:** No "TBD"/"handle edge cases"/"similar to". Every code step shows full code. ✓
+
+**Type consistency:** `ShellState.seed()`, `TurnEntry.new(...)`, `SystemDock.setup`/`_on_handle_pressed`/`_screen_buttons`/`screen_requested`, `NarrationBook.setup`/`narrate`/`show_prose`/`last_degraded`/`_prose`, `MainWindowShell.service`/`book`/`dock`/`_log` — names match across the tasks that reference them. `NarrateResult.display_text`/`facts`/`degraded`, `DmResponse.ok`/`failed`, `FakeTransport.set_response`, `CanonLog.add_fact`/`established_facts`/`set_location`/`push_event`/`active_quests`/`add_humiliation`, `LogPlayer.new`/`PartyMember.new`/`Quest.new` — all match the existing code read during planning. ✓

+# Main Window shell (2a) — design
+
+**Milestone:** M3-b (roadmap "Main Window shell (2a)").
+**Charter:** §2 (code owns state, AI owns text), §16 (mockups are the UI bible), §13 (degraded DM, never an error), §11 (canon log).
+**Mockup:** `mockups/Main Window + Wireframes.dc.html`, option **2a** (the four low-fi wireframes below it are ignored).
+**Branch:** `feature/main-window-shell` off `dev`.
+
+## 1. Goal
+
+The exploration HUD — the frame every other screen lives in. A two-panel "tabletop split": an isometric world view (art slot) on the left, a permanent DM "narration book" on the right wired to the **proven** `/dm/narrate` loop. Around the world view: a turn-order rail, a minimap slot, a slide-in system dock, and a bottom command bar (vitals/gold, quick consumables, End Turn).
+
+This milestone builds the **frame** and its **one live seam** (the DM narration panel). Everything else is faithful placeholder until the milestones that give it meaning (combat, inventory, the individual screens).
+
+## 2. Scope decisions
+
+Settled during brainstorming:
+
+- **DM wire = prose only, with a refire control.** Narrate fires once on scene load to fill the book (considering-state + authored fallback + fact-harvest). One in-world refire affordance (`▸ The Master continues…`) refires it. The numbered response choices and the "describe your own action" free-text line are rendered faithfully but **inert** — there is no action system yet (combat/dialogue are later).
+- **HUD readouts come from a thin, tested `ShellState` model**, not hardcoded scene values. Seed values now; later systems (combat, inventory) become its writers. This is the §2 state seam and the testable core.
+- **System dock buttons are inert.** They emit `screen_requested(id)` (the routing seam) which is a no-op this milestone; the individual screens land later.
+- **Dock slide animation is live** — it is the dock's visual identity and cheap.
+- **Keybind navigation (I/C/J/K/M/P) is deferred** — a shortcut belongs with the screen it opens.
+- **Dock has 6 items** (Inventory / Character / Quest Log / Spellbook / World Map / Party) — faithful to mock 2a. The brief listed 5 (no Spellbook); kept all 6 since the buttons are inert and it costs nothing. Flagged as a reconcile point — Spellbook is not one of the 11 mock screens.
+
+## 3. Architecture
+
+House pattern: **pure, tested cores behind thin scene shims** — the same shape as `DmService`, `ConsideringPhrases`, `MoveValidator` (pure logic unit-tested; the scene/tree wiring is the untested shim, eyeball-gated). Units, each with one purpose:
+
+| Unit | Kind | §2 | Purpose |
+|---|---|---|---|
+| `ShellState` | `RefCounted`, **tested** | state | The HUD data the shell owns: `vitals {hp, hp_max, mp, mp_max, gold}`, `turn_order[]`, `consumables[]`, `round_label`, `location_label`, `dock_open`. Getters + `toggle_dock()`. Seeded now; later systems write it. |
+| `TurnEntry` | `RefCounted` (or a typed dict inside `ShellState`), **tested** | state | One turn-order combatant: `initials`, `initiative`, `is_active`, `is_downed`, `side` (`you`/`ally`/`enemy`). |
+| `SystemDock` | Control scene + script, thin shim | state | The 6 toggle buttons + gold handle. Slide+opacity `Tween`, arrow flip. Emits `screen_requested(id: StringName)` (inert). Toggle drives `ShellState.dock_open`. |
+| `NarrationBook` | Control scene + script, thin shim | text | Right parchment panel. DM header (round · location), prose `RichTextLabel`, placeholder response-choices, inert free-text line, one refire affordance. Consumes a `NarrateResult`; injectable service seam so `FakeTransport` drives it in tests. |
+| `MainWindowShell` | Control scene root, thin shim | — | The two-panel split (1180 world / 740 book). Builds the world side inline (DarkBay iso slot + caption, turn rail from state, minimap slot, mounts `SystemDock`, command bar). Constructs `DmService` + `ConsideringIndicator` and owns the narrate loop. Handles viewport-fit. |
+
+### Reused, not rebuilt
+
+- **Theme:** `client/assets/theme/game_theme.tres`, type-variation names from `ThemeKeys`, colours from `Palette`. Surfaces `ParchmentPanel` / `DarkBay` / `VignetteOverlay` (`client/scenes/theme/surfaces/`).
+- **DM loop:** `DmService.narrate(canon_log) -> NarrateResult{display_text, facts, degraded}`, via `HttpTransport(HTTPRequest)` + `FallbackLibrary`. `DmTransport` is the injectable seam; `FakeTransport` (test double) already exists.
+- **Considering-state:** `ConsideringIndicator.start(label)` / `.stop()` rotates authored phrases at 3.0s.
+- **Seed canon log:** hand-built like `narrate_harness.gd`'s `_build_scene_log()` (`CanonLog` + `LogPlayer` + `PartyMember` + `Quest` + facts/humiliations), until character-creation (M4) and save/load (M9) construct the real one.
+
+### The viewport-fit gotcha (from M3-a)
+
+A root `Control` run directly (F6) is **not** reliably sized by full-rect anchors — it collapses to `(0,0)` and clips everything. `MainWindowShell._ready()` must set `size = get_viewport_rect().size` explicitly (no full-rect anchors on the root) and reconnect on `get_viewport().size_changed`, exactly as `theme_showcase.gd` does. The scene is authored at 1920×1080; display is already `canvas_items` stretch @ 1920×1080, window override 1600×900.
+
+## 4. Data flow
+
+**Load (`MainWindowShell._ready()`):**
+1. `theme = load(game_theme.tres)`; fit to viewport; connect `size_changed`.
+2. Build seed `ShellState` and seed `CanonLog`.
+3. Build the world side (from `ShellState`) and mount `NarrationBook` + `SystemDock`.
+4. Construct `DmService(HttpTransport(HTTPRequest), FallbackLibrary)` and `ConsideringIndicator`.
+5. Fire the initial narrate (below).
+
+**Narrate / refire:**
+1. Disable the refire affordance.
+2. `indicator.start(status_label)`.
+3. `var r := await service.narrate(seed_log)`.
+4. `indicator.stop()`.
+5. `book.show_prose(r)` — set the `RichTextLabel`, surface `r.degraded` subtly.
+6. `for f in r.facts: seed_log.add_fact(f)` (§11 — the caller applies the state write, explicit).
+7. Re-enable the affordance.
+
+Any non-200 → `DmService` already returns the authored fallback (§13); the 35s `HttpTransport` timeout bounds a hang. **No new failure surface.**
+
+**Dock toggle:** handle pressed → `ShellState.toggle_dock()` → `SystemDock` Tweens slide/opacity and flips the handle arrow.
+
+## 5. §2 ledger
+
+- `ShellState`, `dock_open`, HUD numbers, turn order, consumable slots — **state**, client-owned.
+- Narration prose — **text**, consumed from `/dm/narrate`, never a source of truth; only harvested `[FACT]` tags become state (§11).
+- `screen_requested` routing, response choices, free-text line — inert seams; no state written, no text consumed, this milestone.
+
+Nothing in the shell lets an AI response set persistent state directly.
+
+## 6. Testing
+
+TDD via GUT (`cd client && ./run_tests.sh`; `.gutconfig` promotes engine errors to failures — load defensively). New `class_name`s need `godot --headless --import` before GUT sees them.
+
+- **`ShellState`** — seed shape; `toggle_dock()` flips `dock_open`; turn-order and consumable entries have the expected fields/values.
+- **`TurnEntry`** — field round-trip; `side`/`is_active`/`is_downed` flags.
+- **`SystemDock`** — emits `screen_requested` with the correct id per button; toggling updates state (signal + state assertions, no render needed).
+- **`NarrationBook`** — given a `NarrateResult`, sets the prose text and surfaces `degraded`; the refire affordance invokes the injected service (drive with `FakeTransport`, assert prose updates + facts flow out).
+- **`MainWindowShell`** — node-presence smoke (both panels + dock mount); viewport-fit yields non-zero `size`.
+
+**Visual gate (required):** a human F6 run of the shell scene. Headless tests cannot prove rendering — this catches layout/collapse regressions the unit tests can't (the M3-a lesson).
+
+## 7. Out of scope (this milestone)
+
+- Any of the individual screens the dock opens (Inventory, Character, Quest, Map, Party, Spellbook) — inert buttons only.
+- A real action system behind the response choices / free-text line — combat (M5) and dialogue (M6).
+- Real HUD writers (combat vitals, inventory consumables) — seed values only.
+- Keybind navigation, real isometric render, real minimap, real portraits — art slots / later.
+- Save/load of shell state — M9.

Phillip Tarrant	d9caf1dff6	Merge feature/main-window-shell into dev M3-b — Main Window shell (2a): the exploration HUD frame every screen lives in. Two-panel tabletop split — dark world slot (turn rail, minimap, slide-in system dock, command bar) + the permanent DM narration book wired to the proven /dm/narrate loop (prose-only + refire, considering-state, fallback, fact-harvest). Thin tested ShellState; suite 138/138. Establishes the editor-first UI-scene convention (ADR 0001): screens are authored as .tscn node trees, scripts do on-load work only. Theme gained Button-base DockButton/ParchmentButton + a base RichTextLabel prose style.	2026-07-11 10:06:18 -05:00
Phillip Tarrant	c933d12504	docs: record editor-first UI-scene convention (ADR 0001) Capture the direction change from M3-b: UI screens are authored editor-first as .tscn node trees (previewable/arrangeable in the Godot editor), scripts do on-load work only — never build the tree in _ready(). Add ADR 0001, a "UI scene conventions" how-to in client/docs, a §16 mandate in the charter, and mark M3-a/M3-b done in the roadmap.

Phillip Tarrant	58880554c2	fix(shell): dock handle to the right edge; command bar fits Wider consumable tiles overflowed the command bar, shoving END TURN under the dock column. Trim the vitals min-width (230->120) and END TURN (150->140) and separation so the row fits — END TURN lands cleanly at the bottom-right, below the dock. Move the dock handle to the outer (right) side per mock 2a: the menu now sits left of the handle and slides right off-screen to hide, the handle staying at the world's right edge. Dock sits flush to that edge. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 09:59:23 -05:00
Phillip Tarrant	fb541d05cb	fix(shell): widen consumable tiles so labels fit The 62px tiles clipped longer names (Draught, Antidote). Widen to 93px (~1.5x) — there is room in the command bar — so labels fit while tiles stay uniform. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-11 09:50:25 -05:00
Phillip Tarrant	6ef71aaa31	fix(shell): readable ink prose + uniform consumable tiles The narration RichTextLabel had no theme styling, so it rendered near-white and was unreadable on parchment. Add a base RichTextLabel style to the theme (dark INK_BODY serif at 20px, italic face wired) — systemic and previews in the editor; every parchment prose surface now reads as dark ink. Also clip the consumable slot labels so a long name ("Antidote") can't stretch its tile wider than the empty ones — all 8 stay a uniform 62px.

Phillip Tarrant	4698732285	refactor(shell): author shell scenes as editor-previewable node trees Move the three shell scenes (SystemDock, NarrationBook, MainWindowShell) from build-everything-in-_ready() to authored .tscn node trees with the theme + type-variations set in the editor, so the layout previews and can be arranged in the Godot editor. Scripts keep only on-load work: @onready node refs, DM-loop wiring, the dock slide, and binding seed ShellState into the fixed authored turn-order tokens + consumable slots. Fixes the dock offset + over-long buttons (now fixed-width DockButtons in a right-anchored menu). Headless probe: root 1920x1080, world/book split 1180/740, dock at the world's right edge — no collapse. Suite 138/138.

Phillip Tarrant	bca04e3a2e	feat(theme): parchment Button variation for clickable parchment rows ThemeKeys.PARCHMENT_CARD is a PanelContainer-base variation (only a `panel` stylebox) — a Button looks up normal/hover/pressed/disabled, which don't exist there, so a Button styled with it renders unskinned. Add PARCHMENT_BUTTON, a Button-base variation with those four styleboxes plus an empty focus box, built from Palette colours only. Same fix pattern as DOCK_BUTTON for the system dock. Regenerated game_theme.tres from the builder.	2026-07-11 09:07:16 -05:00
Phillip Tarrant	35c4586792	fix(shell): dark DockButton theme variation for the system dock DarkPanel is a PanelContainer-base variation (only a `panel` stylebox); a Button looks up normal/hover/pressed, which don't exist on it, so SystemDock's menu buttons rendered as default gray Godot buttons instead of mock-faithful dark nav buttons. Add a dedicated Button-base DockButton variation (Palette-only colours, dock-dark normal/hover/pressed styleboxes), point system_dock.gd's menu buttons at it, and regenerate the committed game_theme.tres artifact from the builder.
