 * The identity is the app's: a warm-black lab chassis, one colour per rung of
 * the heat ramp, numerals set like a gauge readout. The one rule that keeps it
 * from becoming a generic dark landing page is that colour is *data* here —
 * every accent on a row, a rung or a dot is that thing's real heat, taken from
 * the app's HEAT_RAMP. Nothing is tinted for decoration.
 *
 * The heat colours are per-element custom properties (--c), set inline by the
 * generator from the real figure. CSS never picks one.
