Final polish + verification commit. Tokenises the last hard-coded margin in .fb-question (1.25rem → var(--space-4)) so the spacing scale introduced in commit 1 is the single source of truth. Visually identical (1.25rem === --space-4); the payoff is that any future adjustment to the field-gap token propagates here automatically. Optimistic status toggle was implemented inline in the list (commit 4) and detail (commit 5) pages with a revert-on-failure path — no further sweep needed. Dark-mode QA — verified at 375 / 1024 / 1440 widths via headless Chromium with --enable-features=WebContentsForceDark + --force-dark-mode (token cascade confirmed firing: the rendered gradient matches the dark --gradient-bg in feedback.css, not Chrome's auto-dark inversion of the light gradient): - / — wordmark + tagline + ghost CTA centred, dark-teal gradient ✓ - /login — vertical-centred form, white-on-dark fields, primary CTA ✓ Admin pages and /f/[slug] need post-deploy verification once head merges + deploys this branch — they require auth + a real form slug which the local preview can't supply. The token cascade is shared with these pages so visual regressions are unlikely; functional QA of the optimistic toggle, ⋯ menu click-outside, and share-strip short-link flow should happen against fdbck.msbls.de.
fdbck.msbls.de
Per-link feedback forms and live-chat masks. Anonymous, slug-gated, no auth required for participants.
Spun out from m/flexsiebels.de issue #63 — full design at docs/plans/feedback-feature.md.
Stack
SvelteKit 5 + Svelte 5 + bun + @sveltejs/adapter-node. Postgres + Supabase auth. Schema: fdbck.feedback_{instances,submissions,posts} on supa.flexsiebels.de (msupabase).
Run locally
cp .env.example .env # fill SUPABASE_*

bun run build # adapter-node production build → ./build
Deploy
Dockerfile uses oven/bun:latest. Dokploy app: fdbck.msbls.de. DNS via Hostinger (handled out of band).

Anti-abuse layers
- 32-char base62 slugs (~190 bits entropy)
- in-memory rate-limit (30 posts / 5 min, 10 submits / 5 min, per IP+slug)
- honeypot field on forms + chat (silently dropped)
- body length caps + closing kill-switch
- noindex meta +
