Wires the runtime theme system (CARD_PLAN.md phases 1–7) into the
visible Settings UI so a player can switch between every theme
discovered by `ThemeRegistry` without restarting.
solitaire_data/src/settings.rs
Settings gains `selected_theme_id: String` (default "default"),
guarded by `#[serde(default = "default_theme_id")]` so existing
settings.json files deserialize cleanly.
solitaire_engine/src/settings_plugin.rs
- SettingsButton::SelectTheme(String) variant + focus order 85.
- sync_settings_panel_visibility now reads
Option<Res<ThemeRegistry>>, snapshots id+display_name pairs, and
threads them into spawn_settings_panel. When the registry is
absent (tests under MinimalPlugins) the picker silently skips —
every existing test continues to pass unchanged.
- theme_picker_row helper: like picker_row but keyed by String
rather than usize, with chips wide enough for theme display
names. Attaches the canonical tooltip ("Choose card-face
artwork. Imported themes appear here.") and the FocusRow marker
so Left/Right arrows cycle within the row.
- Click handler updates settings.selected_theme_id, persists, and
fires SettingsChangedEvent — same shape as every other picker.
solitaire_engine/src/theme/plugin.rs
- load_default_theme renamed to load_initial_theme; reads
SettingsResource on Startup and seeds ActiveTheme from
settings.selected_theme_id (falling back to embedded default).
- react_to_settings_theme_change watches SettingsChangedEvent,
no-ops when the active theme already matches, and otherwise
swaps ActiveTheme — the existing
sync_card_image_set_with_active_theme system then refreshes
every card sprite on the next AssetEvent::LoadedWithDependencies.
