- --font-display leads with "Jyotisha Serif SC", then exactly the body
sans stack; no system 宋体 or generic serif (BUG-737 guards kept).
- serif-sc.css imported from site-styles.ts beside globals.css (root
layout also serves admin); swap, no preload.
- Long-form report title (.personal-report-md-article h1) takes the
heading face; deliberate sans headings pinned by a new contract test.
- font-stack-loadable-contract: loadable now includes self-hosted
@font-face with existing files; "no CJK serif" replaced by
"leads with Jyotisha Serif SC, never a system 宋体" (brief T3).
- DESIGN §3, BUG-737 note, CHANGELOG, device checklist, PROGRESS.
