SnapOtterandGitHub 14f6c09805 fix(api): stop palette-quantising PNG output across image routes (#716)
resolveOutputFormat handed every route a default quality of 95, and Sharp reads quality on PNG as palette quantisation, so every PNG through the factory-route family came back dithered and often bigger. quality is now optional and stays undefined for PNG unless a caller passes an explicit override; smart-crop's user-chosen quality still quantises on request.

Two branches bypassed the resolver and carried their own copy of the bug, both fixed: image-pad hardcoded quality 95 for transparent padding, replace-color hardcoded quality 100 when forcing PNG for transparency. pixelate drops the local special case #709 added for the same bug.

Four new integration oracles on >256-colour inputs, each watched failing against the old code.

Fixes #710

SnapOtter b1afcfdf3c test: migrate 207 test files to typed fixture registry (phase 5)
Codemod rewrites all five ad-hoc fixture-path styles to import from the
typed registry (tests/fixtures/index.ts):
- join(__dirname, "..", "fixtures", ...) inline patterns (100 files)
- const FIXTURES = join(__dirname, ...) + join(FIXTURES, ...) (92 files)
- process.cwd()-based paths (10 files)
- path.resolve(__dirname, ...) patterns (5 files)

Registry extended with 8 new keys (portraitJpg, portraitHeic,
motorcycle, svgLogo, barcodeAvif, qrAvif, crossFormatChat,
multipageTiff) and directory accessors (fixtureDir, fixtureRoot).

Dynamic directory scanners (format-matrix-generated,
format-matrix-multimodal, hostile-inputs) preserved via fixtureDir
imports. No fixtures swapped, bytes identical.

Parity gate: dropped 0, net-new 388.

5d8556254f fix: batch file ordering and format preservation for image tools (#20)
* feat: add resolveOutputFormat utility for input format preservation

* fix: preserve file order in batch processing with X-File-Results header

Collect all results before streaming the ZIP to guarantee upload order.
Replace X-File-Order with index-based X-File-Results header that maps
each upload index to its processed filename, handling failures and
duplicate filenames correctly.

Closes #13

* fix: use X-File-Results for index-based batch file matching

The frontend now matches processed files to entries by upload index
instead of fragile name/position matching.

* feat: preserve input format in smart-crop with quality control

Smart crop now outputs in the same format as the input (JPG in, JPG out)
instead of always converting to PNG. Adds an optional quality setting
(default 95) for lossy formats.

Closes #14

* feat: add output quality slider to smart crop settings UI

* feat: preserve input format in crop tool

* feat: preserve input format in color adjustment tools

Applies to brightness-contrast, saturation, color-channels, and
color-effects tool routes.

* refactor: avoid double encode in smart-crop content mode

For the simple trim path (no pad-to-square), chain .toFormat() on the
trim pipeline directly instead of creating a second Sharp instance.
This eliminates a redundant intermediate encode that degraded quality
for lossy formats. Also use trimmed.info dimensions instead of a
separate metadata() call for the pad-to-square path.
