The panel keeps Base Dialog semantics and command wiring while using an industrial poster treatment.

• The opener uses a sky-blue hard-shadow control.
• The top-right X is a dedicated canary-yellow rounded control, not a borderless icon. Its glyph takes the canary fill’s paired foreground, so it stays legible in both themes.
• Hover changes the X to coral and increases its hard shadow.
• Press advances the control 1px in both axes and removes its shadow.
• Footer dismiss actions use the same explicit close semantics; they must not masquerade as neutral text links. Close owns dismissal without a control surface of its own, so the footer action composes a Button child and the composition keeps one tab stop.
• Focus remains a visible hard outline; the accessible Close name is preserved.

The current workspace also inherits the bounded Base Mask pointer-default behavior: participating Mask prevents its root-scoped pointer default from stealing restored focus, while passthrough remains unprevented and Content retains dismissal ownership. This draft revision is separate from any previously published family version; it introduces no new styled Dialog props.
