/* PHOSPHOR: Harness Firmware page
   Material law:
     blue #5FD9FF = volatile: flashes, always decays, never persists
     green #A6FF5E = persistent: committed bytes, the only steady light
     residue #22352A = spent phosphor, latent mass
     bone #E8F4EA = text on glass and the service-paper evidence ground
     glass #070B0C = live runtime state and instrument fields
   Depth comes from dots, grids, hatch, warped linework, and type. No blur,
   glow, glassmorphism, raster stock art, or borrowed reference-site assets.

   Editorial law:
     claim -> evidence -> source -> action; proof precedes exposition
     geometry comes from flat rails, ticks, addresses, and connector boundaries
     numbers remain traceable to facts.json, a repo path, or a measured revision
     CHARGE, DECAY, ROUTE, and RETAIN are the only motion verbs
     alternating glass and service-paper fields make evidence legible
     animated plates are original inline SVG with a useful static end state
     square instrument modules stay native to Harness; no borrowed palette,
     type, mascot, illustration, rounded-card system, or reference-site asset. */
