   --glow-color is the ONE accent used everywhere the glow effect appears:
   the TRAIN tab label, the Drill button, the performance graph's line, and
   (at reduced intensity) a selected mode toggle. It lives at :root only
   because a CSS variable has to be declared somewhere its consumers (the
   tab label, outside #paneTrain) can see it; no rule anywhere in Play reads
   it, so picking it here changes nothing about Play's rendering. Everything
   else Train-specific (background, ink, line colors) is scoped inside
   #paneTrain and never touches --bg/--ink/body.dark, so Play's light/dark
   toggle is unaffected by this section and vice versa.
