# client/scripts/theme/build_game_theme.gd
@tool
extends SceneTree
## One-shot Theme builder. Run headless:
##   godot --headless -s res://scripts/theme/build_game_theme.gd
## Constructs game_theme.tres from Palette + the bundled fonts and saves it.
## The builder is the source of truth; the .tres is a committed artifact.
##
## build_theme() is a static func so it is reachable without saving/quitting —
## tests preload this script and call Builder.build_theme() directly to compare
## a fresh in-memory Theme against the committed .tres (drift guard). Preloading
## a script and calling a static func does not run _init() — only `.new()` does
## — so this is safe to call from a test without side effects.
## §2: presentation.
