/* ---------------------------------------------------------------------------------------------
 * LibelulaBot — the one place colour, type and the shared primitives are decided.
 *
 * Linked by every page, so the landing page and the legal pages cannot drift apart. That drift is
 * what the previous version was already starting to do: two stylesheets, two palettes, no link
 * between them.
 *
 * The palette is a dragonfly's wing — cyan through indigo and violet to pink. It is used for
 * *accent*: headings, numerals, edges, glows. Body text stays near-black on near-white in both
 * themes, because a bright site that is hard to read is not a brighter site.
 *
 * No web fonts. The privacy page tells sellers that nothing about them goes to a third party, and
 * hot-linking Google Fonts would send every visitor's IP to Google and make that sentence untrue.
 * If a display face is wanted later, self-host it.
