/* TRACEGROVE LABS — "Graphite & Silver" (v9, docs/REBUILD-V9.md).
   Ink and graphite carry the brand (header, hero, product stage, proof chapter, footer); cool paper is every
   reading surface. One accent (signal) marks checks, status dots and focus on dark. Serif display, grotesk body,
   mono for data (lot, CAS, MW, mg). Self-hosted OFL faces; metric-matched fallbacks keep the swap free of shift. */
