 * Started from _shared/theme.css (copied, not imported — see that file's header). The two rules
 * it exists to enforce still hold here:
 *   1. Every token is one half of a NAMED PAIR (--X with --X-fg), or carries a contrast: line.
 *   2. Every theme redefines the FULL set.
 * Run `python3 ../../../_shared/check-contrast.py src/styles/` (tools/check.sh does) before
 * calling a change done.
 *
 * contrast: --fg on --bg >= 4.5
 * contrast: --muted-fg on --bg >= 4.5
 * contrast: --muted-fg on --surface >= 4.5
 * contrast: --muted-fg on --surface-2 >= 4.5
