/*
 * site.css: THE LOOK OF THE PURPLE WONTON WEBSITE
 *
 * In plain words: colours, fonts, spacing and layout for every page of
 * purplewonton.com. No fonts or files are loaded from other companies, so
 * visiting the site sends nothing to third parties.
 *
 * Colours ("tokens") are defined once at the top, for light mode and dark mode.
 *   --paper   page background (pale lilac)     --ink     main text (deep plum)
 *   --muted   secondary text                   --line    borders
 *   --wonton  brand purple (links, buttons)    --dup     red, used for duplicate tabs
 *   --keep    green, used for the tab that stays
