/* The key page (spec 7). Colours come from themes.css and the eclipse mark and the buttons from site-parts.css, both generated from the public
   site (tools/sync-portal.mjs); this file is the page's own layout, written by hand. System fonts only, no remote anything, no inline style:
   the content policy allows only this origin and Cloudflare's widget. Secondary text uses --text2 everywhere (the tertiary tone does not
   reach 4.5:1 on a panel lit by the sun). The eclipse is the progress bar: the moon moves with --phase, by transform and opacity only. */
