Five env vars, all with defaults sized for this deployment (84 series
at a 1h cadence). Bad values log and fall back rather than failing
startup, and the cooldown is floored at 15m. Fetches go through
tls-client with a Chrome profile as defence in depth.
Adds a password-gated browser UI for the bookmark list, served by the same Go
binary and container as the userscript API.
## What
- `GET /` — list page, or the login page when there is no session (200, no redirect).
- `POST /login`, `POST /logout` — stateless HMAC session cookie, 60-day Max-Age.
- `GET /ui/list?tab=all|fav`, `POST /ui/bookmarks/{key}/favorite`,
`POST /ui/bookmarks/{key}/chapter`, `DELETE /ui/bookmarks/{key}` — htmx fragments.
- `GET /static/*` — embedded `style.css`, `htmx.min.js`, `filter.js`.
Mobile-first dark CSS, 2–3 column grid at ≥900px, "Continue reading" strip of the
five most recent series, NEW badge, client-side title search, no build step.
## Stack
Go `html/template` + htmx 2.0.4 (vendored, 50 KB) + plain CSS. No npm, no bundler.
Templates and assets are `go:embed`-ed, so `CGO_ENABLED=0` and the distroless
image still hold.
## Auth
`WEB_PASSWORD` gates the UI; unset means the web routes are never registered and
`/` returns 404. Session cookie is `HttpOnly`, `SameSite=Lax`, `Secure` when the
request is HTTPS. The signing key derives from `API_TOKEN` + `WEB_PASSWORD`, so
rotating either logs every browser out. Login is rate-limited to 10 failures per
20 minutes per client IP, keyed on the **rightmost** `X-Forwarded-For` entry
(Traefik appends the observed peer, so the leftmost is client-spoofable). CGNAT
lockout is a known, accepted limitation — the window self-heals.
## Invariants preserved
- A session cookie never authenticates `/bookmarks*`. That API stays JSON +
bearer token, unchanged, as does the userscript.
- `Store.Upsert` is byte-for-byte unmodified. Every UI write goes
read-modify-write through the new `Store.Get`, so the conditional-`updated_at`
rule (favouriting must not reorder the list, a chapter override must) lives in
exactly one function.
## Deployment
`docker-compose.prod.yml` gains a second Traefik router on `MANGA_WEB_HOST`
pointing at the same service — one container, one certificate resolver, no second
service. Both `MANGA_API_HOST` and `MANGA_WEB_HOST` are required (`:?`), with no
example fallback in `.env.example`: a placeholder there would make Traefik
silently publish the UI on a domain you do not own. Needs a DNS A/AAAA record for
`manga.<domain>`. See `DEPLOY.md` §1b.

## Verification
`gofmt` clean, `go vet`, `go test -race ./...`, `CGO_ENABLED=0 go build`, a real
`docker build` + curl smoke test, and a Playwright pass covering login
reject/accept, favourite-without-reorder, chapter edit, delete-with-confirm,
search, tab switch + back button, 390px with no horizontal overflow, and zero JS
console errors.

Add traefik.enable + Host/entrypoints/tls/certresolver/service labels to the
prod override, driven by MANGA_API_HOST / PROXY_NETWORK / TRAEFIK_ENTRYPOINT /
TRAEFIK_CERTRESOLVER env vars (documented in .env.example).
