/* ==========================================================================
   STORYBOOK — Build with it (Design Completion Campaign, 2026-09-29).
   The board is a picture book: openings of two facing leaves bound at a
   gutter, one question to a page, read in order. Faces are the room's own
   ("Brygada X", declared in x-storybook.css); colours come from the grammar's
   tokens. Every class is gsb- or scoped to .gm--storybook.
