Event flow, listeners, gesture recognizers, timers, keyboard handling, and drag-and-drop.
STRVCT provides two layers for handling user interaction: event listeners that wrap native DOM events and forward them to handler methods on views, and gesture recognizers that interpret sequences of events as higher-level gestures like taps, pans, and pinches. A managed timer system supports deferred work with both strong and GC-friendly weak timeouts.
Most application code uses gesture recognizers rather than raw event listeners. The gesture system unifies mouse and touch input, handles multi-touch emulation on desktop, and coordinates competing gestures through a global SvGestureManager.

View →Managed timeout system for scheduling deferred work, with support for weak references to avoid preventing garbage collection.
View →Keyboard state tracking, modifier-aware key dispatch, and the responder chain for focus management.
View →Browser drag-and-drop support for views and nodes, covering both drop targets and drag sources.
