lobo 108cea0491 feat(boids): add boids and particle life demo 
Add linkLabel to AlgorithmEntry. The info panel shows it instead of
"Wikipedia" when set, for links that are not Wikipedia.
Tick the boids item in ROADMAP.md and add a Boids 3D item.

Roadmap

Open ideas for the playground frontend. Tick a box when done.

Quick wins

  • Labyrinth grid size crash: labyrinth.component.html still binds [gridRows]; typed sizes above the max crash the page. Same fix as pathfinding (clamp in code, drop the binding).
  • Fourier circles slider thumb: at "Circles: 256" the thumb sits near the left end, like at 30. Check max/value binding of the circles mat-slider (seen 2026-10-14, not verified).
  • Lighthouse gate: add an assert block to lighthouserc.json (e.g. performance, accessibility, SEO >= 0.9). Today CI runs the audit but never fails. Note: the @lhci/cli → lighthouse 13 override in package.json is only safe without assert. Check it again before you add one.
  • robots.txt + sitemap.xml: static files in public/, listing all routes from app.routes.ts.
  • SEO per algorithm page: all algorithm routes use data: { seo: 'ALGORITHMS' }. Give each one its own key and add SEO.<KEY>.TITLE / DESCRIPTION to en.json and de.json.
  • nginx security headers: no CSP, X-Content-Type-Options, Referrer-Policy, frame-ancestors in nginx.conf (gzip done). First check with curl -I https://andreas-dahm.eu/ if the reverse proxy already sets them.

Tests

  • seo.service.ts: spec for title/meta update on route change and language change.
  • Pure logic without specs: pathfinding-animator.ts, cloth and pendulum GPU strategies (the math around them, not the shaders), fractal3d.

Features

  • Shareable demo state: keep demo settings in query params (fractal zoom/center, sorting algorithm, seeds). Opening the link restores the view.
  • New algorithm demos (pattern: route + RouterConstants + AlgorithmsService entry + i18n + information panel):
    • Boids / flocking (GPU path like cloth)
    • Boids 3D (later, 2D done)
    • Voronoi / Delaunay
    • A* vs Dijkstra side by side (reuse pathfinding)
    • Fourier epicycles
    • Reaction-diffusion (Gray-Scott) shader (reuse the fractal shader setup)
