mmintelandClaude Opus 5.5 90120b60db feat: the homepage leads the visitor through as one story

The page was a row of sections to scroll past, and a film in one of them did
not change that. It now follows the questions a visitor has, in the order
they come up: who is this, can he do what I need, what does it look like,
what else, how does it go, has he done it, what is open, how do I start.

Each chapter ends by asking the next question as a large link that leads on,
and the next chapter answers it. A rail at the edge shows every chapter as a
station with a dot travelling along it (on phones: a pill with the current
chapter and one tap to the next), and the header names the current question.

Where the visitor is, is pure logic in src/domain/chapters.ts. The scroll
film section and the bridge sentences are removed.

Raw Blame History

mintel.me

Personal website of a senior freelance engineer. Next.js 16 (App Router), pnpm monorepo. App lives in apps/web. Social media videos live in apps/video (Remotion, standalone, own CLAUDE.md). Concept and scope: apps/web/plans/freelance-relaunch.md (read it first).

Commands (run from repo root)

pnpm --filter @mintel/web typecheck — must pass with zero errors
pnpm --filter @mintel/web test — unit specs (Vitest); 0 tests run counts as a failure
pnpm --filter @mintel/web test:coverage — src/domain must stay at 100%
pnpm --filter @mintel/web test:mutation — Stryker on src/domain, ~2 min, must score 100
pnpm --filter @mintel/web lint

How to work here (spec first)

Write the behavior as concrete cases (inputs, outputs, edge cases, errors) as a *.spec.ts.
Run it and confirm it fails for the right reason (missing behavior, not an import error).
Implement the simplest clean solution, run again.
Run typecheck, coverage and mutation. Survivors mean weak specs or dead code: fix one or the other.
Report the exact commands and results. "Done" means they were run on the current code. Never weaken, skip or delete a test to make it pass.

Copy rules (client-facing pages)

Never mention AI as the owner's tool, and no internal method vocabulary (specs, TDD, mutation, coverage, pull requests). The automation service may name AI as part of what the client gets. Plain language.
Modest and factual: no promises the owner did not confirm, no superlatives. See the concept, section 1.
Two content pages. The homepage tells one story from top to bottom (who, what you need, examples, how working together goes, results, questions, contact); each section opens with a bridge sentence from story in the content files that leads over from the one before. The technical sections (project fit, tools, how a change is secured) live on /freelance (/en/freelance), for people who develop themselves or lead a team. Do not move technical detail back onto the homepage.
The header has the link to the freelance page, the language switch and "Get in touch", which jumps to the contact section (#contact). Contact is one email address: no calendar integration, no form. The only other pages are the imprint and the privacy notice. URLs of the previous site redirect to / (see next.config.mjs).
Title, description and link previews come from site in src/content/de.ts and en.ts. The share image is a screenshot of the real hero, one per language: after changing the hero headline or its design, run pnpm --filter @mintel/web share-image and commit the PNGs in src/assets/share/.
The email address is kept in parts (src/content/site.ts) and assembled in the browser by EmailLink. Never write the full address into markup, metadata or copy.
The hero design (binary-digit headline) is approved: do not change its design.
Look at the result before reporting: take screenshots (desktop and mobile), do not ship blind.

Two languages (German is the main one)

German lives at the root (/, /freelance, /impressum, /datenschutz), English under /en (/en/freelance, /en/imprint, /en/privacy). The app directory renders both under app/[locale]; proxy.ts maps the public addresses onto it. All routing and detection rules are pure functions in src/domain/routes.ts and locale.ts.
Detection: an address without a language follows the lang cookie (set only by the language switch), then the browser's Accept-Language, then German. /en/... is never redirected.
Every visible text is data in src/content/de.ts and en.ts (type Content in types.ts). Components hold no texts: server components take them from contentFor(locale), client components from useContent(). A new text goes into both files; German uses the formal "Sie".
Never name a file src/i18n.ts or i18n/request.ts: @mintel/next-config would switch on next-intl.
The privacy notice describes the language cookie; keep it true when the detection changes.

Motion (binary micro-interactions)

Building blocks live in apps/web/src/components/bits/: DecodeText (mono labels resolving from digits), BitWipe (headline revealed behind a column of digits), BitReveal (picture assembling from bits), BinaryTicker, ScrollBits, BitBurst, BitCurtain (the language switch transition), BitAura (light along the edge of an element, digits drifting off it; glow only on dark surfaces, on light ones just a few blue digits), BitSeam (lit top edge of a dark section), BitGlow (light following the pointer on data-glow surfaces). Reuse them instead of inventing new effects.
The homepage is a guided story (apps/web/src/components/story/): it follows the questions a visitor has (story.chapters in the content files). Each chapter ends with NextChapter, the next question as a link that leads on; StoryGuide is the rail with one station per chapter and a travelling dot (a pill on phones), and the header names the current question. Sections become chapters through data-chapter (Block prop chapter). Where the visitor is, is computed in src/domain/chapters.ts. A new section on the homepage needs a chapter and a question, or it breaks the thread.
DecodeText is for monospaced text only; in proportional type the changing glyph widths make text jump.
Never put an in-view trigger on an element that clips itself away (clip-path): a fully clipped element never counts as visible. Observe an unclipped wrapper (see BitWipe).
Every effect must respect prefers-reduced-motion and leave content readable without JavaScript.

Architecture rules

Functional core, imperative shell. Pure logic goes in apps/web/src/domain/ (no I/O, no clock, no randomness, no framework imports; pass today etc. in as arguments). Everything there is covered 100% and mutation-tested. Pages, routes and adapters stay thin and call into the core.
Parse at the boundary into precise types (Result, discriminated unions); no nullable state bags.
No any, @ts-ignore, ! non-null assertions or eslint-disable to silence errors. Fix the cause.

Do not

Read or edit .env* (only .env.example). Never print or log secrets.
Commit scratch files (tmp*, *.log, *.tmp, debug HTML, build output). They are gitignored; keep it so.
Use --no-verify, force-push, push to main, or run reset --hard, clean, rm -rf without asking.
Edit .gitea/workflows/* or deploy config without asking.
Upgrade vitest past 4.1.x: @stryker-mutator/vitest-runner 10.0.0 runs zero tests per mutant under vitest 5 and reports false survivors. Re-verify mutation results after any tooling bump.
Add dependencies for trivial things, or touch unrelated code (no drive-by refactors).

Gotchas

tsconfig includes .next/types: after deleting a route, stale generated files there break tsc. Run next typegen and remove the stale file.
Run only one Stryker process at a time; parallel runs share .stryker-tmp and hang.
Stryker needs plugins listed explicitly in stryker.config.json (pnpm layout) and ignores the large asset folders via ignorePatterns; keep them in sync when adding top-level folders.
@mintel/* packages are link: dependencies on a sibling at-mintel checkout. The app itself now only uses @mintel/next-config; the other entries in package.json are leftovers from the old site.
Pushing main deploys to the testing environment; production is deployed from a v* tag.
Git branches: work on feat/*, never directly on main.
