# Changelog

## 0.4.0 — package-native application contract

- Corrected `AppHeader` against the production Launcher two-layer geometry: 68 px outer toolbar and 48 px visible row.
- Made the Launcher header preset strict and added reusable `HeaderNavigation`, workspace and profile primitives.
- Added `useApplicationWorkspace` and `createApplicationWorkspaceController` so navigation/content open, close and expand behavior is shared instead of reimplemented per application.
- Added `MediaSourceField` and a DOM media-source controller from the common Launcher/CMS file/URL/preview pattern.
- Added reusable `SettingsCard` and `Switch` patterns and an executable media/settings catalog section.
- Added the package consumption contract and recorded the boundary between reusable UI and application storage/domain adapters.
- Made all published ESM entrypoints directly importable outside Vite by emitting explicit `.js` module specifiers.

## 0.3.0 — launcher application template

- Rebuilt the living catalog as a Launcher-style windowed application instead of a long documentation page.
- Added the fixed three-axis AppHeader, central media stage and reusable ApplicationShell/ApplicationPanel exports.
- Added Guideline navigation with separate expandable content windows and removed the product-specific bottom service rail.
- Added a responsive mobile panel/modal flow and verified it at a 390 × 844 viewport.
- Added the audited Icon component, 42 semantic glyphs, a living icon table and machine-readable icon registry.
- Reused the Launcher stage media as an optimized MP4 with a static mobile/poster fallback.

## 0.2.0 — source-faithful geometry

- Corrected the Hub header to the production three-axis shell with workspace, navigation and profile groups.
- Added the reusable Hub administration navigation panel and its adjacent-content layout.
- Added integrated and Engine split Select variants with source-accurate dropdown geometry.
- Fixed Engine Environment Settings metrics, accent sections, ranges, checker and action layouts.
- Made right-side inspectors modeless by default: no page dimming, backdrop close or scroll lock.
- Updated the living catalog and registry from the audited source files and supplied screenshots.

## 0.1.0 — baseline
