sulthan af07314bb6 Cinder pass across /admin, the login gate, and the library's a11y floor
Uncommitted work from three design runs on this branch, against one design
system: docs/design-system.md is updated to match the CSS, not the reverse.

Library (Reader-facing):
- .chrome sticks at top: 0. Search and the tab row were unreachable three
  screens into a 300-item library, which is exactly where they earn their
  keep; everything above them still scrolls away on purpose.
- One :focus-visible ring (2px --paper) on the nine controls that defined
  none and fell back to the UA blue. .searchbar keeps its border recolour as
  a resting cue but no longer stands in for a ring.
- Mono labels lift 10px -> 11px everywhere. The brief names night reading and
  glare as the usage scene; 10px small-caps was where taste overrode it.
- A card in flight past 2s says "Saving..." and carries aria-busy. htmx sets
  neither, so the wait up to its 15s timeout was silent in both channels.
- Titles clamp at 3 lines; .is-new .title takes width: fit-content, or
  -webkit-box stretches the ember underline past the text it sizes to.

/admin:
- Overview routes into Lanes when a lane is unhealthy, prefixes each figure
  with its column word on the phone layout that drops the thead, labels state
  cells for a screen reader, and has an empty state where the sites table
  assumed rows.
- The admin shell picks up the library's chrome: htmx 15s timeout, the shared
  #notice slot, #sr-announce, filter.js. admin.css follows the same pass.
- admin_render_test.go and card_render_test.go render the templates directly,
  so markup regressions in either surface fail without a browser.

Login:
- DISCORD_GUILD_NAME (optional) names the community on the login screen and
  in the refusal message, so a stranger knows which Discord to ask for an
  invite. Unset degrades to a generic label; neither form names the guild id.

Handlers:
- maxChapterNum (9999) bounds both typed-chapter paths. uiChapter and
  adminSeriesCorrectLatest each parsed a float64 with no ceiling, so a
  hand-rolled POST stored 1e308 and every later reader of that row inherited
  it. Matches the max on the card's chapter input.

go test ./... green.

Users

Members of one private Discord guild, each with their own library. Accounts exist and are created by signing in — there is no signup form, no invite code and no approval step: any member of the configured guild becomes a Reader on their first Discord login. The person running the deployment is the owner, seeded at startup, and the only Reader with an administrative capability (/admin — Overview, Lanes, Readers, Series).

Reading happens on asurascans.com, demonicscans.org, comix.to and kagane.to for manga and novelfull.com and lightnovelworld.net for novels, primarily via Bromite on mobile, with checks and corrections from a desktop browser. The web UI is the cross-device view into progress the userscripts capture while reading.

Product Purpose

Tracks read-progress ("last chapter read") per series across sites that each have their own separate localStorage. A Go backend unifies bookmarks into one store; the web UI is a Discord-gated browser view of one Reader's own bookmarks, for reviewing, favouriting, correcting, shelving or removing them, and jumping back into a series to continue reading. A background poller refreshes each series' latest-published-chapter so the list can flag "NEW" without the Reader visiting the site.

Positioning

Not a public reading tracker or social app — a private, self-hosted sync layer for one Discord community, purpose-built for a fixed set of scraped sites. Multi-Reader, not multi-tenant: libraries are isolated, but the deployment belongs to one group and its membership is the whole access model.

Operating Context

  • Primary reading device: Bromite (mobile Chromium), where a userscript captures progress automatically. Each Reader installs their own copy, rendered with their own credential.
  • Web UI is a secondary surface: checking list state, correcting a wrong chapter number, removing dead bookmarks, jumping to "continue reading."
  • Cover art and titles come from the source sites' og:image/og:title — real content, not placeholders. They are facts about the series, so they are shared between Readers who track it; progress is not.
  • List order is driven by updated_at, which moves only on real reading progress (not favouriting, not a newly detected chapter) — a UI constraint the design must not break.

Capabilities and Constraints

  • Two libraries (manga, novels) with lifecycle tabs: All / Updated / Favourites / Archived. Search-filter by title (client-side, filter.js).
  • Card actions: continue (opens source site), toggle favourite, manual chapter override, archive, remove — each move out of the list confirm-gated.
  • "Continue reading" horizontal strip for series with an unread chapter.
  • A Reader with no bookmarks at all sees a deliberate empty library offering both userscript install links, not an error and not a blank page.
  • Isolation is the load-bearing invariant: two Readers cannot see or change each other's bookmarks. A series both track is one shared row polled once, with independent progress on each side.
  • The owner alone can reach /admin (Overview, Lanes, Readers, Series) for library/lane/series maintenance and Reader session/Sighting controls; otherwise nothing else in the UI differs by Reader.
  • htmx-driven partial updates, no client-side framework or build step — templates are Go html/template, go:embed-ed.
  • Mobile-first is a hard functional constraint (primary device is a phone), not just a starting breakpoint.

Brand Commitments

  • Name: BookmarkManager.
  • Dark-first is binding: dark-by-default / light-follows-system-preference must be preserved as a design constraint, not just a starting default, because reading happens at night.

Evidence on Hand

  • Live templates/CSS at backend/internal/web/templates/*.html, backend/internal/web/static/style.css, governed by the Cinder design system (docs/design-system.md).
  • No logo beyond the wordmark, no screenshots, no marketing copy; none should be fabricated.

Product Principles

  • Dark-first, night-reading-optimized — never regress to a light-default or high-glare surface.
  • Mobile is the primary target; desktop is an enhancement, not the design center.
  • Progress data integrity over visual flourish: updated_at/list-ordering behavior is a correctness constraint the UI must respect, not decorate over.
  • A leak between Readers fails silently and looks like working software — isolation is asserted from both directions, never inferred from counting one Reader's rows.
  • No roles, no org chrome beyond the owner gate: /admin is the one owner-only console (Overview, Lanes, Readers, Series) for library-wide hygiene, lane health/pauses and series/Reader maintenance — Readers offers revoke sessions and clear Sighting marks, both confirm-gated — and otherwise every Reader's view is the same.
  • Prefer native platform affordances (system dark/light, native touch targets) over custom widgetry — this is a lean self-hosted tool, not a product to demo.

Accessibility & Inclusion

Explicit personal requirement: optimized for low-light/night reading — minimize glare and eye strain (true dark surfaces, restrained brightness/contrast on accents, no jarring pure-white flashes), beyond generic touch-target/contrast compliance.
