Extract static, state-free subtrees into standalone View structs to
prepare for .equatable() memoization in Phase 5:
- FeatureBox: extracted from MainMenuPage's private featureBox() method
- ContainerTypesRow: Card/Box/Panel examples from ContainersPage
- SettingsAndAlignmentRow: settings panel + alignment demos
ButtonsPage left as-is — nearly all sections depend on @State clickCount
through Button actions, making decomposition ineffective for memoization.
AppHeader is rendered at the top of the terminal by RenderLoop, similar to
StatusBar at the bottom. Views declare header content via .appHeader { }
ViewBuilder modifier. Supports standard (thin divider) and block (half-block
with appHeaderBackground) appearance. Hidden when no content is set.
Diff cache invalidates on header height changes to prevent ghosting.
Update IDETemplateMacros.plist and replace headers in 136 Swift files with
new format: 🖥️ TUIKit — Terminal UI Kit for Swift. Remove sdsd.swift template draft.
Auto-animating loading indicator with three visual styles:
- Dots (braille rotation), Line (ASCII rotation), Bouncing (Larson scanner
with fade trail). Time-based frame calculation ensures each spinner runs
at its own speed independent of render triggers.
Configurable: SpinnerSpeed (.slow/.regular/.fast), BouncingTrackWidth
(.minimum/.default/.maximum/.fixed(Int)), BouncingTrailLength
(.short/.regular/.long), custom color.
Run loop upgraded from 100ms to 40ms polling (~25 FPS) to support
smooth animations.
