# XWUIImageSlot

Design-tool image slot: filled = cover image; empty = dashed placeholder with
caption. Parent must be `position: relative` (or otherwise establish a
containing block). Inline geometry prevents a CSS race from flashing the
image at intrinsic size.

Unlike `XWUIImage` (standalone picture) and `XWUICaptureFrame` (titled frame
around a capture), this is the absolute-fill slot primitive.

## Origin

Ported from the Alamiya corporate site marketing image-slot pattern.
