Tracks read progress on comix.to and kagane.to alongside asura and demonic, in both the userscript and the backend.
Implements `docs/superpowers/plans/2026-08-03-comix-kagane-support.md`.
## Userscript
- `comix` adapter — `/title/<id>-<slug>`; only the id prefix is identity (the slug follows the title). No `og:image`, so the cover is matched by `alt`.
- `kagane` adapter — reader URLs are uuids with no chapter number, so it comes out of `og:title`; anchor scanning is structurally impossible, replaced by `latestChapterFromApi` against kagane's same-origin JSON API.
- `seriesId` threaded through `latestChapterFromAnchors` so comix can scope its scan to its own series and a recommendation strip cannot win the maximum.
- `@match` for both hosts, panel chips, v1.6.0.
## Backend
- `latestChapterFrom` cases: comix parses the SSR JSON state blob (`latestChapterUrl`, scoped to the series id); kagane parses API JSON (`chapter_no`).
- Poller allowlist extended; `Poller.BrowserFetch` with `fetcherFor(site)` routes kagane to a browser fetcher. Nil means kagane is not polled at all — never a fallback to the TLS fetcher, which would only ever retrieve a challenge page.
- `BrowserFetcher`: chromedp against a `headless-shell` sidecar. kagane sits behind a Cloudflare JS challenge that no TLS fingerprint clears, and the request is made inside the page rather than by replaying `cf_clearance`.
- `BROWSER_WS_URL` wiring, sidecar in both compose files (no `ports:`, dedicated non-external network), Dockerfile on `golang:1.26-alpine` — chromedp requires go 1.26.
- Web UI `--comix` / `--kagane` tokens in both colour branches.
## Notes for review
- `series_url` is client-supplied and a headless browser is a strong SSRF primitive, so kagane's host is pinned twice: in `fetchableSeriesURL` and again in `kaganeAPIURL`.
- Three chained defects found during verification made the browser path dead under Compose (sidecar flag collision, Chrome's Host-header DNS-rebinding check, the wrong chromedp option). Fixed; the compose comments record the wrong configurations too, so they don't get "simplified" back.
- `ALLOWED_ORIGINS` now includes both new origins. Without it every write from comix/kagane silently fails CORS preflight, parks in the retry queue, and drops at the cap.
## Verification
221 backend tests, 32 userscript tests, static `CGO_ENABLED=0` build, both compose configs.
Two gaps, both real:
1. The userscript on live pages via Violentmonkey needs a human browser profile — not run. Check: comix series page (title/cover, no chapter), comix chapter page (records the number; an *older* chapter must not regress it), comix SPA navigation without reload, kagane series page (og:image cover), kagane reader (number from `og:title`), both chips opening the right sites.
2. The kagane browser path has not completed end-to-end anywhere. Dial/navigate/fetch is confirmed, but Cloudflare 403'd headless-shell's Chrome on every attempt from the dev sandbox, and comix's poll-through-Docker was blocked by that environment's TLS interception. Both environment-dependent rather than branch defects — the first real deploy is the actual verification.

Drops the Continue and Edit buttons, makes the card body the continue target, adds a confirm to Remove, replaces the view-blocking circular FAB with a 7x44 edge tab plus a two-finger long-press, and adds a zero-dependency node:test harness for the adapter logic. Fixes a latent offsetWidth/offsetHeight bug in the FAB placement math. No backend or API change.
Verified live against real asurascans.com and demonicscans.org series and chapter pages: edge tab does not cover artwork, card-body click navigates, action buttons do not, Remove confirms and cancel preserves the row, the 25s dwell fill records progress, and the tab drags/snaps/clamps correctly.
Known and accepted: a deliberately slow two-finger pinch that stays inside the 15px slop for the full 500ms opens the panel. A normal-speed pinch (240px in ~240ms) cancels well before the timer. An absolute per-finger drift threshold cannot separate a slow pinch from two fingers resting, which is the gesture being detected.
