/* eidovelle.com
 *
 * The whole site is five static HTML files, one stylesheet, two self-hosted fonts, and no
 * JavaScript at all. That is not minimalism for its own sake. The product's argument is that it
 * is more careful than its category, and the two claims this site makes about itself, that
 * nothing here flashes and that nothing here watches you, are both claims a reader can only
 * verify by looking at what the page loads. A page with no script and no third-party request can
 * be checked in about ten seconds. A page with either cannot be checked at all.
 *
 * _headers carries the machine-readable half of the same promise: default-src 'none' means the
 * browser refuses a script even if one were added to a page by accident.
 *
 * Palette and faces come from ios/Eidovelle/UI/Theme.swift, so the site and the app are the same
 * object rather than two things that resemble each other. The semantics from that file hold here
 * too: the dark is the field, brass is the instrument, teal is what you sail toward. Nothing
 * structural is teal and no world is brass.
 */

/* The fonts are subset copies of the exact variable TTFs the app bundles. Rebuild with
 * web/tools/build-fonts.py. swap rather than block because the safety copy is the reason
 * somebody is on this page, and it should be readable in a local serif before it is beautiful. */
