/* Hallmark · Postli shared system · Obsidian theme v1.1 (Graphite)
 * Loaded by every marketing + legal page. Imports tokens.css first.
 * Provides:
 *   1. Legacy var aliases — old --bg / --fg / --accent names map to new tokens
 *   2. N5 Floating-pill nav and Ft5 Statement footer (the cross-site chrome)
 *   3. Restyled legacy class names (.btn, .card, .pill, .section, .page-hero…)
 *      so existing pages inherit the new look without HTML rewrites
 * Tokens-only — no inline OKLCH / hex values past this comment.
