/* Skimora site tokens. Palette and roles come from the extension's own theme
 * (C:\skimora\src\ui\theme.css), so the site and the product read as one thing:
 *
 *   sage  = identity: logo, headings' quiet accents, ticks
 *   mark  = LIVE. The highlighter. It is the reading highlight and it is the buy
 *           button, on purpose: the button glows the same colour as the thing it
 *           sells. Used as a background, never as text.
 *   ink   = text
 *
 * Nothing else on the page is warm, so anything apricot is either "happening now"
 * or "this is how you get it".
