 * Styles for the pairnest.app landing page (index.html and pl/index.html).
 *
 * Hand-authored, like the two pages that use it: the generator in
 * src/features/legal/ owns everything under /legal/ and nothing here.
 *
 * The colour values mirror src/design/design-tokens.ts, which is the source
 * of truth for the app. They are repeated as literals because this page ships
 * without a build step — nothing compiles the token module into CSS here.
 * When a token changes there, change it here too; the names are identical so
 * the pairs are greppable.
 *
 * The Penpot boards for this page live on page "07 Landing" of the mockup
 * file. Note that Penpot's own theme-light set still carries the pre-AA
 * values, so the hexes below come from the code, not from the boards.
