/* CoreTools documentation - shared stylesheet.
   Palette pulled directly from dcc/maya/theme.py's own Color class, so
   these docs read as the same visual family as the apps they describe -
   not a copy of AM2x-CF's palette (which drifted from CoreTools' own
   over the course of this project), just its overall layout language:
   kicker + h1 + subtitle header, h2 dividers, feature-grid cards, code
   blocks with a monospace stack. */
