/*
 * Angelia landing — styles
 *
 * Tokens are inlined from packages/theme/tokens.css rather than @imported: a
 * second stylesheet is a second blocking request, and the performance budget
 * in docs/LANDING.md is part of the argument the page is making. Keep the two
 * files in sync; every value below carries its computed WCAG ratio.
 *
 * HARD RULE: --ichor (#eebc15) is 1.57:1 on --pentelic. It gilds edges and
 * seals. It is NEVER text on a light surface. See docs/BRAND.md.
 *
 * Dark-first: ichor is AAA (9.95:1) on Nyx and unusable as text on marble, so
 * dark is the mode the metaphor was designed for.
