/* dash.css — ON1 dash, "mission control" surface.
 *
 * 12th distinct aesthetic surface (CLAUDE.md variety rule):
 *   index → cyberpunk · panel → utilitarian dashboard
 *   aedln0d → Swedish-newspaper · aedln0d/kg → engineering schematic
 *   healthlog → terminal sparklines · docs → warm-paper editorial
 *   metacyc → orrery · syskg → sys-kg gallery
 *   timeline → observatory logbook · ssmailab → SSM-magenta gov light
 *   nrs → IAEA quiet/diplomatic slate (warm parchment)
 *   dash → MISSION CONTROL / RADAR WALL  (this file)
 *
 * Register: dark navy ground, cool cyan accents, hex-grid texture,
 * subtle scan-pulse glow on active tiles. The page is a *portal*
 * showing summary cards for every installed dashboard; clicking a
 * tile expands the surface into an embedded iframe inline (no
 * navigation), so the operator never loses the dash context.
 *
 * No innerHTML in the sibling JS. Pure stdlib for any backend probes.
