- ui/src/error.html: custom SvelteKit last-resort fallback (replaces
  the bare '500 | Internal Error' shown when +error.svelte itself fails)
  — branded, auto-refreshes in 20s, book+lightning SVG illustration
- ui/src/routes/+error.svelte: improved with context-aware SVG
  illustrations (question mark book for 404, lightning bolt for 5xx),
  larger status watermark, and a Retry button on non-404 errors
- caddy/errors/500.html: new static error page matching the 502/503/504
  design — served by Caddy when a gateway-level 500 occurs
- Caddyfile: add handle_errors 500 block pointing at /srv/errors/500.html
- caddy/Dockerfile: COPY errors/ into image so static pages are baked in
