/* ──────────────────────────────────────────────────────────────────
   Recording overlay (REC-045)

   Full-screen mobile-only overlay that takes over the viewport for a
   single recording attempt: recording → paused → uploading →
   upload-success → (uploaded, overlay tears down).
   Failed → user dismisses via the close button.

   Activation: .recording-screen.is-active. The mobile / phase guard
   is on the Alpine binding side; CSS just reacts to the class.

   Token palette comes from theme.css (--color-accent / --color-accent-dark
   / --color-accent-soft / --color-bg / --color-text / --color-text-muted /
   --color-primary).

   pointer-events keep it inert when not active; the visibility transition
   is delayed only on the way out, so click events don't leak in mid-fade. */
