/// inkpal_bridge example — bridge showcase.
///
/// A 9-zone Flutter app exercising every capability the bridge exposes to
/// an AI assistant. Each zone is built around realistic patterns an AI
/// would see in real apps: layout bugs, error-handling foot-guns, form
/// flows, scrollable lists, runtime state, visual-regression baselines.
///
/// Zones:
///   • Core Debug      — overflow, constraints, rebuild loops
///   • Visual Debug    — clipped text, contrast, tap-target sizing
///   • Auto-Fix        — patches the bridge can suggest + apply
///   • Runtime Intel   — live tree, state, timers, gesture conflicts
///   • Error Intel     — throw paths the catcher should map
///   • Visual Testing  — golden + regression + responsive
///   • Developer Exp.  — chat, inline hints, history surfaces
///   • Smart Assist    — a11y, responsive, animation suggestions
///   • Forms & Input   — fields, scroll, switches, sliders
///
/// Run with:
///   `flutter run -d <device>`
