feat(theme): the creation screen's five variations

SelectCard (a Button whose `pressed` IS the chosen ring), SkillChip (a toggle
with unpicked/picked/granted-so-inert), the CHOSEN and PRIMARY tags, and the
gold PrimaryCard ring. Plus INK_LABEL_MUTED for the sheet's section headers.

Built by build_game_theme.gd and regenerated; the .tres is never hand-edited.
