Tasks: enterprise-react-image

Change ID: enterprise-react-image Package: @suaveplan/react-image Target path: react/media/react-image Prerequisite packages on Verdaccio: @suaveplan/error, @suaveplan/react-translate

0. Pre-flight (non-negotiable)

0.1 Confirm clean working tree (git status reports nothing) and no in-flight worktrees with uncommitted work (git worktree list then git status in each)
0.2 If any worktrees exist under .claude/worktrees/, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (git worktree remove) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
0.3 Confirm the package set in MANIFEST.md matches find packages -maxdepth 3 -name package.json count. Drift here means a prior change archived without regenerating the manifest.

1. Scaffold

Create directory tree per proposal layout.
Write package.json at 0.1.0 with "sideEffects": false, exports map.
Dependencies: @suaveplan/error workspace:^, @suaveplan/react-translate workspace:^, zod catalog:forms, @opentelemetry/api catalog:observability, tslib catalog:build.
Write tsconfig.json, vitest.config.ts, scripts.

2. Error codes and types

Define ImageError extending SuaveplanError; codes: IMAGE_LOAD_FAILED, IMAGE_DECODE_FAILED, IMAGE_CROP_INVALID.
Define all component prop types in src/types/.

3. Utils

src/utils/blurhash/ — decodeBlurhash(hash, width, height): Uint8ClampedArray, blurhashToDataURL(hash, width, height): string. Write test + md.
src/utils/filter-presets/ — getFilterCSS(preset: FilterPreset): string (grayscale, sepia, blur, brightness, contrast, invert). Write test + md.

4. Hooks

For each hook (useImageLoader, useImagePreloader, useImageDimensions, useImageColor, useLightbox):

Implement hook. useImageLoader emits OTel image.load span. Throws ImageError on failure.
Write test (≤500 lines) + stories (playground) + md. { timeout: 10000 }.

5. Components

For each component:

Implement with i18n via useTranslation, forward ref, a11y attributes.
Image — lazy loading via IntersectionObserver, blurhash placeholder, skeleton fallback, srcSet.
Avatar/AvatarGroup — initials fallback, status indicator (online/offline/busy/away), group overlap.
ImageComparison — draggable split slider; keyboard adjustable.
ImageCropper — drag-handle crop selection; validates bounds (throws ImageError(IMAGE_CROP_INVALID) on invalid).
ImageFilter — CSS filter presets via getFilterCSS; preview toggle.
ImageGallery — masonry layout via CSS columns or absolute positioning.
ImageMagnifier — hover-activated lens at configurable zoom level.
ImageOverlay — gradient/reveal overlay wrapper.
ImagePlaceholder — SVG with aria-label.
Lightbox — portal-rendered; keyboard nav (Left/Right/Esc); thumbnails; close on backdrop.
ZoomImage — pinch-to-zoom (touch) + wheel-zoom; pan when zoomed.
Write test + stories (default, loading, error, interactive, playground) + md for each.

6. E2E

e2e/image.spec.ts — Playwright:
- Image with lazy-load: scroll into view → img src set.
- ImageCropper drag: drag handle, verify crop rect changes.
- Lightbox: click image → lightbox opens; press Right → next image; press Esc → closes.
