 *
 * Aesthetic flavor: BIOHAZARD-CYAN (new flavor, 17th surface).
 * The mental image is a petri dish under a UV stereo microscope —
 * faint hexagonal cell-grid, cyan colonies pulsing on dark teal,
 * IBM Plex Mono labels next to organic curves. Distinct from
 * terminal-octagonal (aiaas), stargate-orbit (welcome), engineering-
 * schematic (aedln0d/kg), warm-paper-editorial (docs).
 *
 * Color story:
 *   void:   #031014  (deep teal-black, almost ocean-floor)
 *   panel:  #062021  (chamber wall)
 *   phos:   #00e5d9  (live colony cyan — primary brand)
 *   phos2:  #4dffe3  (highlighted edge)
 *   bio:    #7df7c5  (mid-green growth)
 *   alert:  #ff7280  (death / refund warning)
 *
 * No innerHTML in companion JS; this file is the visual contract only.
