/* ghost-overlay.css — Ghost View resting glow (Phase 2.1).
 *
 * Admin-only travel overlay on the calendar grid. The glow is painted as a
 * ::before layer on the day cell, sitting BETWEEN the cell's background and its
 * content: the ::before is z-index:0 while the cell's direct children (date
 * number + chips) are raised to z-index:1 — so chips and the date stay fully
 * readable and are never obscured. The glow's colour + brightness are composed
 * per-cell in calendar-ghost-overlay.js (hue = resource, brightness = leg
 * volume) and handed in via the --ghost-bg / --ghost-ring custom properties.
 * Companion: public/calendar-ghost-overlay.js.
