Notification email (to Dennis):
- Complete dark-theme redesign: #0c0c0c bg, #141414 card, gradient top bar
- Sender avatar with liquid-mint/sky gradient + initial letter
- Subject displayed as pill badge
- Message in styled blockquote with mint left border
- Gradient "Direkt antworten" CTA button
- replyTo header already set so email Reply goes directly to sender
Telegram notification:
- sendTelegramNotification() fires after successful email send (fire-and-forget)
- Uses TELEGRAM_BOT_TOKEN + TELEGRAM_CHAT_ID env vars (silently skips if absent)
- HTML-formatted message with emojis, name/email/subject/message preview
- Inline keyboard button "Per E-Mail antworten" with pre-filled mailto link
- Never blocks the contact form response if Telegram fails
Reply email templates (respond/route.tsx):
- Same dark design system as notification email
- baseEmail() generates consistent header + footer
- messageCard() helper for styled message blocks with colored left border
- ctaButton() helper for gradient CTA buttons
- Templates: welcome, project, quick, reply — all updated to dark theme
Required new env vars:
TELEGRAM_BOT_TOKEN=<from @BotFather>
TELEGRAM_CHAT_ID=<your chat/user ID>

The Hero server component awaited getMessages(locale) which called Directus
with a 2-second timeout. On testing.dk0.dev (or when Directus is unreachable),
this blocked the entire Hero render for ~2s → LCP 3.0s / 2320ms rendering delay.
Changes:
- Hero.tsx: remove getMessages() call entirely; use t() for all strings
- messages/en.json + de.json: add hero.badge, hero.line1, hero.line2 keys
- lib/i18n-loader.ts: invert lookup order — JSON first, Directus only as
override for keys absent from JSON. Previously Directus was tried first
for every key, causing ~49 parallel network requests per page load in
HomePageServer (aboutT + projectsT + contactT + footerT translations).
Now all JSON-backed keys return instantly without any network I/O.

- Replace next-themes (38 KiB) with a tiny custom ThemeProvider (~< 1 KiB)
using localStorage + classList.toggle for theme management
- Add FOUC-prevention inline script in layout.tsx to apply saved theme
before React hydrates
- Remove framer-motion from Header.tsx: nav entry now uses CSS slideDown
keyframe, mobile menu uses CSS opacity/translate transitions
- Remove framer-motion from ThemeToggle.tsx: use Tailwind hover/active scale
- Remove framer-motion from legal-notice and privacy-policy pages
- Update useTheme import in ThemeToggle to use custom ThemeProvider
- Add slideDown keyframe to tailwind.config.ts
- Update tests to mock custom ThemeProvider instead of next-themes
Result: framer-motion moves from "First Load JS shared by all" to lazy
chunks; next-themes chunk eliminated entirely; -38 KiB from initial bundle

overflow-hidden on the <section> was clipping the -bottom-6 badge
and the image bottom on iPad viewports where content sits near the
section edge. Move overflow-hidden to the blobs container (absolute
inset-0) so the blobs are still clipped but the image and badge can
render freely. Add pb-10 sm:pb-16 bottom padding so the badge always
has clearance.

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

CI:
- Replace `npm run build` with `tsc --noEmit` in test-build job
→ eliminates duplicate Next.js build (~5 min saved per push)
→ Docker deploy job already does the full build
PageSpeed:
- Add `cssChunking: 'loose'` to merge CSS into one chunk and break
the 84dc7384→3aefc04b render-blocking CSS waterfall chain (450ms mobile)
- Remove @shadergradient/react, @react-three/fiber, three from
package.json — packages were already unused in code, removes any
residual bundling risk for chunk 7001
Hero:
- Change lg:flex-row → xl:flex-row so iPad (1024px) stays in column
layout; the 9.5rem heading overflowed into the image at lg causing
the photo to be clipped by overflow-hidden on the section
- Update image sizes attribute to match new xl breakpoint
- Fix contrast: "GET IN TOUCH" link text-stone-500 → text-stone-700
(contrast 3.7:1 → 7:1, now WCAG AA compliant)
- Change text-center/justify-center to xl: variants to match layout

Adds the missing env vars to deploy-dev so testing.dk0.dev has
access to Directus CMS data (projects, books) and n8n features,
matching the production container configuration.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add POST /api/n8n/hardcover/sync-books — n8n calls this after detecting
finished books in Hardcover. Authenticates via N8N_SECRET_TOKEN/N8N_API_KEY,
deduplicates by hardcover_id, creates new book_reviews entries in Directus.
- Add getBookReviewByHardcoverId() + createBookReview() to lib/directus.ts.
Check uses GraphQL filter; create uses Directus REST POST /items/book_reviews.
- ReadBooks: replace silent return null with a visible empty state so the
section stays visible with a hint until the n8n sync populates it.
- Projects: add "No projects yet." placeholder instead of blank grid when
both Directus and PostgreSQL return no data.
- Add home.about.readBooks.empty i18n key (EN + DE).
n8n workflow setup:
Schedule → HTTP Hardcover GraphQL (books_read) → Code (transform) →
POST /api/n8n/hardcover/sync-books with array of { hardcover_id, title,
author, image, rating, finished_at }

- Replace ShaderGradientBackground WebGL shader (3 static spheres) with pure
CSS radial-gradient divs — moves from ClientProviders (deferred JS) to
app/layout.tsx as a server component rendered in initial HTML. Eliminates
@shadergradient/react, three, @react-three/fiber from the JS bundle.
Removes chunks/7001 (~20s CPU eval) and the 39s main thread block.
- Remove optimizeCss/critters: it was converting <link rel="stylesheet"> to a
JS-deferred preload, which PageSpeed read as a 410ms sequential CSS chain.
Both CSS files now load as parallel <link> tags from initial HTML (~150ms).
- Update browserslist safari >= 15 → 15.4 (Array.prototype.at, Object.hasOwn
are native in 15.4+; eliminates unnecessary SWC compatibility transforms).
- Delete orphaned app/styles/ghostContent.css (never imported anywhere, 3.7KB).
- Add .claude/ dev team setup: 5 subagents (frontend-dev, backend-dev, tester,
code-reviewer, debugger), 3 skills (/add-section, /review-changes,
/check-quality), 3 path-scoped rules, settings.json with auto-lint hook.
- Update CLAUDE.md with server/client orchestrator pattern, SSR animation
safety rules, API route conventions, and improved command reference.

requestIdleCallback is unavailable in Safari < 16.4, causing GatedProviders
to crash during hydration and blank the entire page. Added setTimeout fallback.
Also added IntersectionObserver fallback in ScrollFadeIn for safety.

ScrollFadeIn uses IntersectionObserver + CSS transitions instead of
Framer Motion's initial prop. Key difference: no inline style in SSR
HTML, so content is visible by default. Animation only activates
after client hydration (hasMounted check).
Wraps About, Projects, Contact, Footer in HomePageServer.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Framer Motion's initial={{ opacity: 0 }} was rendered as inline
style='opacity:0' in SSR HTML. If client-side JS failed to hydrate
properly, sections stayed permanently invisible.
Removed whileInView scroll animations from About, Projects, Contact.
Modal animations (AnimatePresence) kept as they only render on interaction.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
dynamic() caused Framer Motion's initial opacity:0 to be baked into
SSR HTML, but client-side hydration never triggered the animations.
Direct imports ensure Framer Motion properly takes over on hydration.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
ssr:false caused sections to only render client-side, making them
invisible if any JS error occurred. Keep dynamic() for code-splitting
but allow server-side rendering.

The dev-deploy workflow was trying to spin up separate portfolio_postgres_dev
and portfolio_redis_dev containers, which don't exist on the server. Now it
reuses the existing production portfolio-postgres and portfolio-redis on
the portfolio_net network.

Mount .next/cache as a BuildKit cache volume during build to persist
the Next.js build cache across Docker rebuilds. Eliminates the
'No build cache found' warning and speeds up subsequent builds.

Make prisma migrate deploy failure non-fatal in start-with-migrate.js.
Previously, migration failure caused process.exit() which killed the
container, triggering an infinite restart loop. Now logs a warning
and starts the Next.js server anyway (app has DB fallbacks).

- Disable Sentry in all 3 configs (client/server/edge) - replayIntegration
was recording every DOM mutation causing overhead in Chrome
- Remove grain-overlay div and its CSS (SVG feTurbulence + mix-blend-mode:overlay
forces software compositing in Chrome on every frame)
- Remove mix-blend-multiply from BackgroundBlobs (prevents Chrome GPU compositing)
- Delete unused Grain.tsx, ShaderGradientBackground.tsx and its client wrapper

ShaderGradientBackground used 3 full-screen Three.js WebGL canvases
with a blur(150px) CSS filter, crashing Lighthouse and causing severe
lag in Chrome. BackgroundBlobs also had 7 elements with blur(100-120px)
and per-frame mouse spring tracking compounding the issue.
- Remove ShaderGradientBackground from layout (WebGL not needed for a blur effect)
- Reduce BackgroundBlobs blur from 100-120px to 60px
- Remove mouse tracking spring animations from BackgroundBlobs
- Reduce to 4 blobs (remove 3 least visible)

- Add `prefix` param to checkRateLimit/getRateLimitHeaders so each endpoint
has its own bucket (previously all shared `admin_${ip}`, causing 429s when
analytics/track incremented past n8n endpoints' lower limits)
- n8n/hardcover/currently-reading → prefix 'n8n-reading'
- n8n/status → prefix 'n8n-status'
- analytics/track → prefix 'analytics-track'
- Remove custom analytics system (AnalyticsProvider, lib/analytics,
lib/useWebVitals, all /api/analytics/* routes) — was causing 500s in
production due to missing PostgreSQL PageView table
- Remove analytics consent toggle from ConsentBanner/ConsentProvider
