/*
 * site.css — the site's only stylesheet (loaded by src/layouts/BaseLayout.astro).
 *
 * Design adapted from mattrothenberg.com: a single narrow column, big
 * Instrument Sans paragraphs, small semi-condensed uppercase section labels,
 * pill "company badges" with a rotating colour glow on hover, and Paper Mono
 * list rows separated by hairlines.
 *
 * Classes are prefixed `ed-`; <body> carries `.ed`. Light/dark is driven by
 * the `data-theme` attribute on <html> (set before paint by BaseLayout and
 * toggled/saved by SiteFooter), falling back to the OS preference.
