/*
 * site.css — Hemly satellite site (COLD_START §4).
 *
 * Tokens are the same values as `src/styles/tokens.css` (DESIGN_SPEC §1); only the
 * subset a marketing page needs is copied here, because this site is a standalone
 * static bundle with no build step for CSS. If the palette changes, change it there
 * first — tokens.css stays the authority.
 *
 * Rules this file obeys:
 *   - no Vinted teal (#007782 family) anywhere (docs/CLAUDE.md §红线 5)
 *   - system font stack only, no @import, no Google Fonts, no external request at all
 *   - money is tabular and the largest thing on the card
 *   - light theme only, matching the extension
