/* manual.css — FreeCut user manual.
 *
 * Self-contained on purpose: the manual must stay readable by someone who is
 * still deciding whether to sign in, so it carries its own palette rather than
 * pulling tokens.css. That is why the values below repeat instead of inherit.
 *
 * MANUAL.html is hand-maintained as of 2026-10-03; the old
 * scripts/build_manual.py generator is not in the release tree.
