# Changelog

All notable changes to the public design kit surface are documented here.

## Unreleased

### Added

- Submodule-first repository layout (`kit/`, `exports/`, `tools/designsync`, `demo/`)
- Initial bundle manifests (`ai-rules`, `bible-core`, `go-web-skeleton`, `ui-pattern-table`, `ui-pattern-modal`)
- `designsync` MVP CLI (`list`, `validate`, `plan`, `apply`)
- Demo app (`demo/`) with bundle catalog UI
- Design single-source index: `bible/architecture/design-canon-map.md`
- Active reusable Vapor theme module in `kit/patterns/theme-vapor` (CSS + icon sprite)
- New export bundle: `ui-theme-vapor`
- Vapor shell palette catalog with 9 preset IDs for header/accent colors and tokenized shell height
  (`kit/patterns/theme-vapor/palette-catalog.md`)

### Changed

- Canonical baseline docs aligned to `Vapor Soft` / `Vapor Night` as active demo/scaffold style.
- Aqua module/docs clarified as legacy archive/reference (not active baseline).
- Table-management docs clarified as theme-agnostic geometry/semantics contract.
- Vapor shell CSS now supports reusable preset selection via `data-vapor-shell` and shared
  `--shell-*` tokens across default, auto-dark, and explicit `data-theme` modes.
- Demo/scaffold runtime now includes a deterministic vapor preset selection strategy:
  `?vapor_shell` → `localStorage["vapor_shell"]` → markup default.
