/* Theme for the OSO download host's directory listings.
 *
 * nginx's fancyindex module generates the page: a <title>, this stylesheet, then
 * the header fragment, an <h1>Index of ...</h1>, a <table id="list">, and the
 * footer fragment. Setting fancyindex_css_href REPLACES the module's built-in
 * stylesheet entirely, so everything the listing needs has to be here.
 *
 * Matched to web/oldschoolops (ink-950 ground, one #46ff00 accent, Space Grotesk
 * headings) so a visitor who arrives from the main site does not feel like they
 * left it. The palette is duplicated rather than shared, because this file is
 * served by a different machine that has no access to the site's build.
