LayoutTimer
Legacy polling-based layout timer that detects size and visibility changes.
Compat shim for the old LayoutTimer / Serenity.LayoutTimer API. Polls registered elements every ~100 ms,
supports optional debouncing, and fires handlers when width, height, or visibility transitions occur.
Prefer ResizeObserver or Fluent.on(..., 'layout') with CSS-based layouts for new code.
[DEPRECATED] Kept for backward compatibility with legacy layoutFillHeight and triggerLayoutOnShow callers. Use ResizeObserver instead.
