/**
 * OpenStation — AI Assistant spotlight overlay.
 *
 * A system-level command palette that floats above the entire shell,
 * including the WP admin bar. Visually modeled on macOS Spotlight and
 * Linear's command menu — frosted-glass backdrop, spring-physics panel
 * entrance, large search input, accent-tinted header.
 *
 * z-index 10000 puts this above --os-z-adminbar (9991) so the
 * overlay truly covers the full viewport.
 *
 * ## Desktop-theme awareness
 *
 * The overlay mounts on `document.body`, so it sits inside the
 * `body.os-desktop-theme-<slug>` half of a compiled theme's
 * doubled selector and every `--os-ui-*` token below resolves against the
 * active theme. Each site reads `var( --os-ui-x, <the literal that was
 * always there> )`, so an unthemed shell paints exactly as before.
 *
 * Getting this half-right is worse than not doing it at all: when the
 * text tones followed the theme but the panel stayed hardcoded white,
 * a dark theme's light `--os-ui-fg` landed on white and the results were
 * unreadable. Any new surface added here MUST take its background,
 * border and text from the palette — not from a literal.
