/* ============================================================
   SRDELI — Multiview (multiview-fs.css) v3.1
   ------------------------------------------------------------
   DESIGN PRINCIPLE: The stage is INVISIBLE.
   Only tiles are visible. Empty space shows the page background.

   OVERLAY LAYOUT (top-left to right):
   [drag-handle] [name-label · viewers]     [X-remove]
   All overlay elements share opacity behavior:
   hidden by default, shown via .mv216-show-overlay,
   :hover, :focus-within, .is-dragging, .is-drop-target.

   JS INLINE-STYLE CONSTRAINTS:
   - layout(): sets left/top/width/height on slots (plain)
   - alignSuggestBox(): !important left/top/width (viewport coords)
     → suggest must be position:fixed
   - hardenNativeFrameFullscreen(): !important on fullscreen frame
