   HELP SECTION ONLY — main marketing site keeps its crimson identity.
   This file is loaded via <link> and deliberately styles everything under
   .help-body via high-specificity rules so it cannot be defeated by browser
   cache of earlier attempts.

   Palette (ONLY these four families — no crimson, no teal, no amber):
     BLACK   #000000 #0A0E14 #12161D  (base, surface, surface-2)
     BLUE    #2563EB #3B82F6 #60A5FA #1E3A8A  (primary, hover, accent, deep)
     WHITE   #FFFFFF #F9FAFB #E5E7EB  (heading, body, secondary)
     GREY    #D1D5DB #9CA3AF #6B7280 #374151 #1F2937  (greys 300→800)

   Logo: TEXT only. No inline SVG — zero risk of unsized expansion.
