What's New at Lab Grimoire

ANOVA, T-Test, Correlation, PCA, and Linear Regression tool pages: H4 sub-sections collapsed into bold lead-in paragraphs; depth now caps at H3
Protocols index, Blog index, and home page: added screen-reader-only H2s so the H1 → H3 jump is gone (better for AI Overviews and accessibility)
New site-wide rule (CONTENT_TYPOGRAPHY.md): three-level heading ceiling (H2 → H3), ≤5 H2 on teaching pages; hub and legal pages exempt
New CI check: bun run check:headings (scripts/check-heading-hierarchy.ts) blocks future violations

Flow Cytometry Analyzer is now a Pro feature; the tool grid shows a Pro chip on gated tools and anonymous visitors see an upgrade card instead of the full app
Grimoire and Spell Book both gained a quick filter bar: search, category, top-15 tag chips, plus time window (blog) or minimum rating (spellbook)
Both listings paginate at 6 items per page — pages load less data and feel snappier
Article cards now show the actual go-live date (first_published_at) instead of whatever date was set during drafting
Performance: the Flow Cytometry bundle (~285 KB) only downloads after the Pro check passes — anonymous visitors no longer pay its cost
Reliability: new /api/cron/health endpoint surfaces scheduling pipeline status; D1 migrations now auto-apply on every deploy to prevent silent schema drift
Bug fix: the home page no longer throws a CSP console warning on the View All Tools button
