/*
 * Crew Pitboard theme on top of Pico.css v2.
 *
 * A dark "timing screen" look: near-black background, high-contrast text and
 * one accent colour (racing red). The layout forces dark mode with
 * <html data-theme="dark">, so only the dark variables are set here.
 *
 * Classes:
 *   .site-header        header bar with the wordmark and the navigation
 *   .wordmark           the "Crew Pitboard" logo text (.wordmark-lg: big, centred)
 *   .centered, .narrow  body / container for the signed-out card pages
 *   .nav-link           a <button> that looks like a nav link (log out)
 *   .inline             a form that sits inline in text or a list
 *   .btn-small          a compact secondary button (e.g. "Remove")
 *   .muted, .lead       secondary text, intro text
 *   .accent             text in the accent colour
 *
 * Landing page:
 *   .hero, .actions     intro block and its row of buttons
 *   ol.steps            numbered "how it works" cards; a grid on wide screens
 *   ol.guide            numbered setup instructions
 *   article.download    download card: text on the left, button on the right
 *
 * Leaderboard (#7):
 *   form.filter         track and class pickers in a row (.filter-actions: buttons)
 *   section.board       one track layout + car class (.board-head: its heading)
 *   td.driver           driver name; .driver-meta under it shows car and date
 *                       on phones, where .col-car and .col-date are hidden
 *   tr.me               the signed-in driver's row
 *   .badge-record       the "Record" tag on the track record holder's row
 *   .empty              the "no laps yet" / "nothing matches" notice
 *   .laptime            a lap or sector time: monospace, tabular figures
 *   .gap                a gap to the leader ("+0.412"), muted .laptime
 *   table.timing        a timing-screen table
 *   tr.p1 / .p2 / .p3   podium rows: gold, silver and bronze edge + position
 *   .pos                the position cell
 *   .badge              car-class badge; colour by class with
 *                       .badge-hypercar, .badge-lmp2, .badge-lmgt3 (GT3),
 *                       .badge-gte; plain .badge for anything else
