v1.3.0

v1.3.0

Tailwind CSS v4 migration plus guided-view, library and styling fixes.

Changed

• Tailwind CSS v3 → v4 (build): the engine moves to tailwindcss 4.3.3
  with the new @tailwindcss/cli package. Configuration is now CSS-first
  (styles/tailwind.css; tailwind.config.js removed) and the markup uses
  v4 utility names (shadow-xs, bg-<color>/NN, shrink-0,
  bg-linear-to-r, ...), with values verified against the v3 stylesheet.
• Browser support floor (compat): Tailwind v4 requires Safari 16.4+,
  Chrome 111+, Firefox 128+ (or equivalent). Earlier browsers will not
  render styles correctly.

Added

• Guided view zoom improvements (reader): dialogue bubbles magnify 3.2×
  with width clamping to avoid clipping text; full-width panels (≥ 1.35×
  base scale) zoom with an adaptive overlay height that eliminates black
  voids.
• Manga speech-bubble detection (guided view): a dedicated ONNX speech
  bubble detector now runs for manga mode, with detected bubbles persisted
  to the guided-view sidecar.
• Sidecar lifecycle management (guided view): <id>.json sidecars are
  migrated and synced when a comic is renamed or its folder is moved (in-app
  and on disk), corrupted sidecars are cleaned up, and missing guided-view
  generation is auto-queued.

Fixed

• Unbounded reading-lists refetch (library): with zero reading lists,
  the filter-count refresh and the list cache re-triggered each other in a
  loop (~200 req/s of GET /api/v1/reading-lists) that drained the server
  rate limiter. An in-flight guard plus a loaded flag stop the loop, while
  explicit refetches (Reading Lists modal, mutations) still work.
• Border and focus-outline parity under Tailwind v4 (style): v4's
  outline-none drops v3's transparent 2px fallback used in forced-colours
  mode, so all 25 focus sites now use outline-hidden; a base-layer shim
  restores v3's gray-200 default border colour.

All changes passed the full test suite (71 suites / 528 tests) before
release.
