Changelog

0.4.0

Added the unified Toolbox top bar with a centered app title, standard Help and Gitea source controls, Personalize, and Apps switching.
Added persistent System, Light, and Dark appearance choices shared with the Toolbox Portal.
Added a real dark CodeMirror configuration with dark editor surfaces, gutters, active lines, and syntax highlighting.

Upgraded Toolbox Contract, React Shell, and Testkit dependencies to 0.2.0.
Replaced the app-specific Help and Source actions with the shared shell controls and manifest repository fallback.
Converted workbench controls, cards, diagnostics, dialogs, tables, and editor chrome to semantic theme variables.

Added a typed Toolbox Contract v1 application definition and generated toolbox-app.json manifest.
Added the shared React application shell while retaining the XSLT-specific Help action.
Added standalone and toolbox-mode integration coverage, including nested-path static deployment checks.
Added deterministic, cross-time-zone release ZIP and SHA-256 generation with complete production dependency licence files.
Added a session-only SHA-256/revision trust gate that disables both transformation engines until the exact stylesheet is reviewed and confirmed.
Added conservative transformation input/output limits and a best-effort asynchronous deadline.
Added a prominent Source action and corresponding-source notice for the 0.3.2 tag.

Made Vite build assets relocatable with a relative deployment base.
Resolved the lazily loaded SaxonJS runtime relative to the deployed application path.
Documented that the vendored SaxonJS 2.7 browser distribution is free to use under separate, non-open-source terms and is not part of the application's AGPL licensing.
Classified stylesheet processing conservatively and documented that executable stylesheets may access browser or network resources.
Documented that trusted SaxonJS can access same-site Toolbox data, send data over the network, or navigate away; the recommended portal CSP is defense in depth rather than containment.
Switched Toolbox SDK dependencies from local workspace links to the public token-free package registry.
Release packaging now refuses to overwrite same-version artifacts unless --force is explicit.

Added global keyboard shortcut Shift + Enter to apply the current transformation.
Added global keyboard shortcut F1 to open the help dialog.
Added shortcut hints for transformation and help actions.

Added browser-side SaxonJS dynamic compilation support.
Added support for raw XSLT 1.0, 2.0, and 3.0 transformations through the SaxonJS dynamic engine.
Added dynamic XSLT-to-SEF compilation in the browser using the full SaxonJS2.js browser artifact.
Added lazy loading for the SaxonJS browser compiler/runtime.
Added tests covering XSLT 1.0, XSLT 2.0, and XSLT 3.0 transformation scenarios.
Added project quality commands for type checking, linting, formatting, testing, building, and combined checks.

Made saxon-js-dynamic the primary SaxonJS-based engine for raw XML + raw XSLT workflows.
Removed the earlier failed npm-bundled SaxonJS approach.
Removed the SEF-only SaxonJS placeholder from the main workflow.
Excluded vendored SaxonJS files from linting and formatting.
Cleaned up debug-only code and unused declarations.
Improved transformation engine registry and test coverage.

Fixed SaxonJS browser integration by using the full SaxonJS2.js artifact instead of SaxonJS2.rt.js.
Fixed dynamic compiler setup by providing a synthetic stylesheet base URI.
Fixed SaxonJS static parameter handling by passing an XdmMap instead of a plain JavaScript object.
Fixed browser compiler result extraction by reading checkedOptions.principalResult.
Removed duplicate XML output replacement after transformations.

Added SaxonJS 2.7 as the default transformation engine.
Added lazy loading for the SaxonJS runtime so it is split into a separate build chunk.
Kept the native browser XSLTProcessor engine as selectable fallback.
