/* block-overlay.css — HA-toggled curtain + bottom-right countdown widget.
 *
 * Curtain: 1–4 reason tiles in an auto-sized grid driven by [data-count].
 * Each tile = PCS symbol (yellow PCS bg intrinsic) + word label below.
 * The surround stays black so the yellow tiles read instantly.
 *
 * Countdown widget: small bottom-right ring + MM:SS label. Sits over the
 * playing video, with a translucent dark backdrop circle for visibility on
 * any video frame. Hidden whenever the curtain is up.
