m chose cards over a spacious-list pattern. They're MINIMALIST cards: subtle .fb-card bg on the gradient page bg, no border + shadow stack, generous internal padding, plenty of negative space between cards (1.5rem mobile, 2rem desktop). 2-up at ≥640px so they breathe without widening the shell. Per-row simplifications: - Drop the H2 "Your forms (N)" — the cards are the count. - Drop the descriptive paragraph in the header — single primary CTA on the right is the entire header. - Card title is the link to detail. The "Edit" button becomes implicit. - Subtitle merges mode + counts on one muted line; the "created DATE" line and the raw "/f/<slug>" line both go away (slug is in the menu, date is available on the detail page). - Right side: a clickable .fb-status-pill that flips status optimistically, next to a .fb-menu (⋯ trigger + native <details> panel) holding Copy link / Open / Edit / ────── / Delete. - Optimistic status toggle: pill flips instantly, PATCH fires in background, reverts to server state on failure. Status is reversible so this is safe. - Delete still uses the existing confirm() modal (m's override — no undo toast, deletion remains a deliberate two-step action). - All inline style="..." removed except a tiny hoisted .fb-list-head style block for the header layout. Click-outside-and-Escape close any open ⋯ menu — added via document-level listener in onMount, cleaned up in onDestroy. Empty state gets generous whitespace + a primary "Create your first form" CTA in the .fb-empty container.
fdbck.msbls.de

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 +
