sulthan a587b16423 Web UI: Updated tab, inline errors, mobile card fixes (#3)
Third pass on the password-gated web UI, on top of #1 and #2.

## Updated tab
New `?tab=new` tab listing only series with an unread published chapter, plus per-tab empty states for Favourites and Updated. Covered by `TestUIListNewTab`.

## Inline error feedback
htmx does not swap on a non-2xx response, so a failed favourite/chapter/delete looked like an ignored tap. Errors now render in a `.error-inline` slot on the card and clear after 5s. The chapter-edit form and delete-confirm row also close each other — only one per-card panel open at a time.

## Mobile fixes (P0)
`.chapter-form` held three children on one unwrapped flex row, pushing Save off screen: **97px of page overflow at 390px, 127px at 360px**. That broke correcting a chapter number on the primary device class.

- `.chapter-form` and `.confirm-row` wrap; hint and prompt take their own full-width row
- `.chapter-form input` uses `flex: 1 1 0; min-width: 0` — with `flex: 1` (basis auto) a number input holds its ~20ch intrinsic width and refused to shrink, which pushed Save to a third row
- `white-space: nowrap` on the confirm prompt alone reintroduced 26px of overflow; the full-width row is what actually fixes it

Verified live: `document.body.scrollWidth <= window.innerWidth` with every chapter-form and confirm-row open, at 360/390/768/1280, light and dark.

## Icons
`☆ ✎ 🗑 ▶` replaced with hand-authored inline SVG on `currentColor` — the emoji font rendered each in a different face, weight, and colour, ignoring the card's own type and colour system. `.icon.on` / `.icon.danger` / `.primary` keep driving colour. No icon font or library added.

## No-cover empty state
Series whose source site gave no `og:image` render a title-initial monogram (`Bookmark.Initial()`) instead of a blank `--surface-2` rectangle that read as a cover still loading. Shared between the card cover and the Continue-reading strip.

## Verification
- `go build ./... && go test ./...` — pass
- Live interaction run: favourite toggle round-trips, chapter save 210.5→211, All/Updated/Favourites swap, delete-confirm removes the card, no console errors

Users

Single user (self-hosted, no accounts, no multi-user planned). Reads manga on asurascans.com and demonicscans.org primarily via Bromite on mobile, also checks/updates from a desktop browser. The web UI is the cross-device view into progress captured by the userscript while reading.

Product Purpose

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

Positioning

Not a public reading tracker or social app — a private, self-hosted sync layer purpose-built for two specific scraped sites, with no server-side account system (single bearer token + one password-gated session).

Operating Context

  • Primary reading device: Bromite (mobile Chromium), where a userscript captures progress automatically.
  • Web UI is a secondary surface: checking list state, correcting a wrong chapter number, removing dead bookmarks, jumping to "continue reading."
  • Manga cover art and titles come from the source sites' og:image/og:title — real content, not placeholders.
  • 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 redesign must not break.

Capabilities and Constraints

  • Two tabs: All / Favourites. Search-filter by title (client-side, filter.js).
  • Card actions: continue (opens source site), toggle favourite, manual chapter override, delete (with confirm).
  • "Continue reading" horizontal strip for recently-progressed series.
  • htmx-driven partial updates (card re-render on favourite/chapter/delete), no client-side framework/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: mangaBookmark.
  • Dark-first is binding: current dark-by-default / light-follows-system-preference behavior 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/templates/*.html, backend/static/style.css — current implemented UI, functional but not yet treated as an intentional design system.
  • No logo, screenshots, or marketing copy exist; 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.
  • No accounts, no multi-tenant chrome — the whole product is for one reader.
  • 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.
