/*
 * guide.css — Obiettivi-specific geometry on top of the shared _shared/base.css.
 * Layout and staging ONLY; every colour comes from the --gc-* theme vars so the
 * page follows the player's theme in-app and on the site.
 *
 * Colour grammar used throughout (kept distinct on purpose):
 *   --gc-accent  (blue)   = the player's own things — selection, Objective count,
 *                           the rank a lane will accept next.
 *   --gc-warning (amber)  = the piles you may touch during the refill, and the
 *                           joker's borrowed rank.
 *   --gc-success (green)  = hint highlighting (a card you may play) and "done".
 *   --gc-error   (red)    = the illegal side of a contrast frame.
 * Gold/amber is NEVER used for the next-rank cue: on the real table amber means
 * "touchable pile" and gold means wild, so the next slot is blue.
