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
