/*
 * site.css -- placeholder stylesheet for the scaffold.
 *
 * The colour values below are PLACEHOLDERS. The final palette is decided in
 * the build phase, following the rules in DESIGN.md (one committed accent that
 * is not purple, neutrals with a deliberately chosen temperature, WCAG AA
 * contrast). Everything that needs a colour must read it from a custom
 * property so the palette can be changed in exactly one place.
 *
 * Temperature of this placeholder palette: cool neutrals (a faintly green-grey
 * off-white and a blue-black ink) with one deep green accent.
