- theme.ts mixed symbol presets, JSON schema, color math, the Theme class,
loading, global state, appearance handling and TUI adapters in 3171 lines.
- Symbols, schema, color, theme-class, loader and tui-adapters are now
siblings; theme.ts keeps global state, the watcher, appearance handling and
HTML export at 745 lines, with all 44 exports intact.
- Left appearance and export-colors in place: both read private mutable
auto-theme state, so extracting them would have required new exported
internals or DI rather than a straight move.
