/*
 * Ascent — support site.
 *
 * THE SITE IS THE APP'S OWN DARK, as of 2026-09-08 and by Kevin's explicit
 * call. The first version used the game ART's pale sky, reasoning that legal
 * text reads best on paper and that the app's amber was unreadable at 1.9:1
 * on snow. Kevin wanted the site to feel like the thing you download - same
 * ground, same text, same golds - and the dark ground dissolves the old
 * contrast objection: every token below is lifted straight from the app's
 * src/ui/theme.ts, and gold on this navy sits near 9:1.
 *
 * COLOUR CARRIES THE APP'S OWN GRAMMAR:
 *   gold  = tappable / the climb   (the app's accent, --climb)
 *   red   = the summit, only       (the flag; one appearance per page)
 *   dim   = secondary voice        (the app's textDim)
 *
 * The imagery everywhere is the ICON's mountain - red flag planted. The hero
 * went through three forms in one evening and the simplest won: stepped
 * bar-rules (read as charts), then the playing screen's full painted scene
 * (too busy next to type), then the mark itself, pixel-crisp. The stepped
 * rule is gone from every page for the same reason it lost the hero, and the
 * challenge page carries the same mark instead of a goat frame that read as
 * awkward out of animation. Kevin's calls, 2026-09-08.
