/* Lisaris EO Studio documentation.
 *
 * Palette and chrome follow the API reference at /docs on the API domain:
 * Axine indigo on near-black surfaces, the Axine wordmark in the header bar,
 * the same three-column grammar of sidebar, prose and page contents.
 *
 * Everything is same-origin. Caddy's CSP for the site domain allows
 * style-src 'self' 'unsafe-inline', font-src 'self' data: and
 * img-src 'self' data: blob: https://*.mapbox.com, so there is no external
 * stylesheet, no font host and no image host. Plus Jakarta Sans is vendored
 * beside this file because it is the typeface the product itself uses.
