TipTap (ProseMirror) was causing:
- chunks 1007 (85 KiB) and 3207 (58 KiB) in the initial bundle
- Array.prototype.at/flat/flatMap, Object.fromEntries/hasOwn polyfills
(ProseMirror bundles core-js for these — the 12 KiB legacy JS flag)
- 2+ seconds of main thread blocking on mobile
Fix: move HTML conversion to the server (API route) and pass the
resulting HTML string to the client, eliminating the need to import
richTextToSafeHtml (and transitively TipTap) in any client component.
Changes:
- app/api/content/page/route.ts: call richTextToSafeHtml server-side,
add html: string to response alongside existing content
- app/components/RichTextClient.tsx: accept html string, remove all
TipTap imports — TipTap/ProseMirror now has zero client bundle cost
- app/components/About.tsx, Contact.tsx: use cmsHtml from API
- app/legal-notice/page.tsx, privacy-policy/page.tsx: same
- app/components/ClientWrappers.tsx: change static imports of About,
Projects, Contact, Footer to next/dynamic so their JS is in
separate lazy-loaded chunks, not in the initial bundle
