* feat(a11y): add focus trapping and dialog roles to all modals
* feat(a11y): add toggle switch roles, form labels, and error association
* fix(a11y): fix contrast failures, touch targets, and add nav landmark to sidebar
* fix(a11y): add role=switch to remaining toggle buttons found in verification sweep
- Fix selective metadata stripping (P1): use Sharp's keepExif()/keepIccProfile()
instead of broken withMetadata({}) that preserved everything
- Fix meme font mapping (P1): add ArchivoBlack and ComicNeue fonts, map
arial-black and comic-sans to correct TTF files instead of Anton

Spanish, French, Italian, Brazilian Portuguese, German, Dutch, Swedish,
Russian, Polish, Ukrainian, Arabic (RTL), Turkish, Hindi, Vietnamese,
Indonesian, and Thai.

- ~1500 translation keys per locale with TypeScript-enforced completeness
- Dynamic code-splitting: only the active locale is loaded at runtime
- Language selectors in footer, login page, settings, and mobile sidebar
- Arabic RTL support with CSS logical properties across all components
- Tool names, descriptions, and categories translated via i18n helpers
- Public API endpoint GET /api/v1/config/locale for instance default
- Multi-script font stack (CJK, Arabic, Devanagari, Thai, Cyrillic)
- format() and plural() helpers for interpolation and pluralization
- API error translation mapping (translateApiError)
- 36 Playwright e2e tests verifying all 21 locales load correctly
- 25 unit tests for format, plural, locale detection, and completeness
- Updated translations.md docs and CLAUDE.md conventions
The luminance anomaly detection + LaMa inpainting approach failed because
watermark signal on the matted foreground was too weak (10-15 units vs
threshold of 25). Median filter with kernel=5 effectively removes
semi-transparent watermark text while preserving the stamp structure.
Pipeline is now: median filter (if toggle on) -> BiRefNet matting -> defringe.
No longer requires object-eraser-colorize bundle for watermark removal.
HDR and EXR files decoded by ImageMagick can produce 16-bit PNG buffers.
Sharp's CLAHE operation (hist_local) requires VIPS_FORMAT_UCHAR (8-bit).
Check the buffer depth and convert to 8-bit sRGB before processing.
The find-duplicates tool failed entirely when any uploaded file couldn't
be processed, returning "Duplicate detection failed" or a format-specific
error that aborted the whole batch. With mixed-format uploads (77 files),
this made the tool unusable.
- Skip unprocessable files instead of aborting; return skippedFiles in response
- Switch from fetch() to XHR with upload progress tracking (Uploading X%)
- Add Vite proxy timeout config (5min) to prevent connection drops on large uploads
- Add "Download Grouped" button: ZIP with each duplicate group in its own folder
- Add collapsible skipped-files section in the results UI
- Add 3 integration tests for skip behavior (43 total)
setError() in the file store unconditionally set processing to false,
even when called with null to clear a previous error. This meant
setProcessing(true) followed by setError(null) at the start of
processing would immediately kill the processing state, preventing the
progress bar from ever rendering.
Fix setError to only reset processing when there is an actual error.
This also fixes the same latent bug in 10+ other custom tool settings
components that call setProcessing before setError.
The vectorize tool had a custom processing flow that bypassed the
standard useToolProcessor hook -- no progress indication, no server-side
batch, and the Download All ZIP relied on a client-side sequential loop.
Backend: extract core logic into vectorizeBuffer(), register via
registerToolProcessFn() so the /batch endpoint works with p-queue
concurrency and SSE progress events.
Frontend: replace custom fetch loop with useToolProcessor hook and
ProgressCard, giving upload progress, per-file batch status, and
automatic Download All ZIP via the existing tool-page infrastructure.
Also set image/svg+xml MIME type on SVG blobs during batch ZIP
extraction to ensure reliable rendering in <img> tags across browsers.
Background images, device frames, custom shadows, and watermark text
were not rendering in the right-pane preview. The preview now updates
in real time for all settings: gradient/solid/image backgrounds, macOS/
Windows/Browser frame chrome, iPhone/MacBook/iPad frame indicators,
custom shadow parameters, and watermark text overlay.
Also fixes a React StrictMode effect-ordering race where the parent
tool-page reset cleared preview state set by the child Settings
component on initial mount.
The stitch route only decoded HEIC via ensureSharpCompat, so exotic
formats (DNG, PSD, TGA, BMP, JXL, HDR, QOI, DDS, ICO, JP2, DPX, etc.)
crashed Sharp at metadata read time, causing "Stitch creation failed".
Add the full CLI decode pipeline (decodeToSharpCompat) matching the
tool-factory pattern, plus SVG sanitization with proper error handling
for each format category.
Replace fetch() with XMLHttpRequest in the frontend to surface upload
progress via onprogress events, and add a progress bar that shows upload
percentage then pulses during server-side stitching.
Error from a failed image (e.g. DNG) persisted when navigating to a
previously cached image because the cache path skipped setError(null).
Also pass the original file extension to decodeToSharpCompat so RAW
variants get the correct temp file suffix for ExifTool/ImageMagick.
The compose route only decoded HEIC/HEIF via ensureSharpCompat, causing
EPS, PSD, BMP, RAW, and other exotic formats to fail with
"Processing failed". Now uses the same full format pipeline as the
tool-factory for both base and overlay buffers.
Info panel always read files[0] and stored results in a single useState,
so it never changed when switching images. Now tracks selectedIndex,
auto-fetches on navigation after initial "Read Info" click, caches
results per-index, and aborts stale requests on rapid navigation.
- Refactor use-tool-processor and use-pipeline-processor hooks
- Enhance dropzone component with improved UX
- Improve seam carving with better error handling and tests
- Add JXL format encoding support to format-encoders
- Update tool routes for consistent format handling
- Add dropzone unit tests
- Added isImageFile() filter to all drop handlers (dropzone, collage,
file-upload-area) so PDFs and non-image files are rejected on drop.
Previously only the file picker's accept attribute filtered; drag-and-
drop accepted anything.
- Added ppm, pgm, pbm to CLI_DECODED_FORMATS in file-validation.ts.
These formats were missing, causing Sharp metadata checks to fail for
some files during batch validation, which silently dropped them from
results ("File not found in batch results").
- Added integration tests for PBM, PGM, PPM, TIFF, QOI, JP2, SVGZ
single-file processing, plus a test confirming PDF is rejected.
Small bordered buttons with Minus/Plus icons flank the range slider,
allowing single-step quality adjustments. Disabled at min (1) and
max (100) boundaries.
AVIF was missing from expandAccept() and every inline accept attribute,
causing the OS file picker to gray out .avif files. Drag-and-drop was
unaffected because it bypasses the accept filter. Added .avif to
dropzone.tsx expandAccept (covers all Dropzone pickers) plus 12 inline
accept strings across tool settings, pages, and file-upload-area.
- Remove duplicate "Files" heading (section header + inline count)
- Space "Show more" and "Clear all" apart on the same row
- Replace bare number input with number + KB/MB dropdown for target
size, defaulting to KB; MB values are converted to KB for the API
- Hide native number input spin buttons for a cleaner look
- Preview font size now calculated from actual container width, not viewport
- Preview stroke scales proportionally with font size (4% ratio)
- Server stroke reduced from 6% to 4% to match preview
- Added ResizeObserver to track container width for accurate sizing
- Added paint-order: stroke fill to CSS preview for consistent rendering
