 * design-tokens.css uses `section[style*="bordeaux-900"]` to override .display
 * color to --on-dark. PHP templates use a CSS class instead of an inline style,
 * so that selector never matches. We replicate the override here for all
 * class-based dark surfaces.

/*
 * Bug 2 — External link arrows / Unicode symbols rendering as emoji:
 * Characters like ↗ (U+2197) have both a text form and an emoji form.
 * Browsers pick the emoji form when no font has the text glyph.
 * `font-variant-emoji: text` forces text presentation everywhere it is
 * supported; the HTML `︎` variation selector is the fallback.
