/*
 * Simam Spaces — portal styles.
 *
 * The hub borrows the grammar of the app our creators are leaving: one dark
 * ground (#171717), one typeface in heavy weights, a full-bleed hero, rows of
 * 16:9 cards that scroll sideways, and pill buttons in a single bright blue.
 * The grammar is borrowed; the brand is not — the name, mark and words are
 * ours, and nothing here should be mistaken for anyone else's product.
 *
 * Dark only, on purpose. Every colour is a token on :root and nothing reads
 * `prefers-color-scheme`. The one exception is the roadmap's "paper" surface
 * at the bottom of this file: a long document is read, not browsed, and it
 * redefines the same tokens rather than restyling anything.
