/* ======================================================================
   TRAIN FABRIC — COLOR RULES (strict, do not violate)
   ----------------------------------------------------------------------
   COPPER  = identity, static elements ONLY.
             Primary CTAs, logo, brand headline accents, card top-borders,
             static labels, section underlines.
   CYAN    = EVERYTHING that moves, pulses, or is live.
             All data-flow pulses, all active states, training indicators,
             live counters, hover glows, loading indicators, GPU activity
             pulses, fan glow, every cursor-following or heartbeat animation.
   NEVER mix copper and cyan on the same element.
   Copper is the static brand. Cyan is the heartbeat.
