/* =============================================================================
 * OberBuilt Analysis Engine — [oae_waitlist] public signup card
 * -----------------------------------------------------------------------------
 * Restyled DARK on 2026-10-13 (FE-09, visual audit; owner default D5 = A).
 * The marketing site moved to a dark theme (body #0B1620, cyan accent), and
 * the 2026-09-13 light card keyed on the old child theme's --ob-* tokens now
 * floated as a white box on a dark page, with every var(--ob-*) resolving to
 * its fallback because the new theme defines no --ob-* names at all.
 *
 * SOURCE OF TRUTH: the plugin's OWN tokens (assets/css/tokens.css, --oae-*),
 * which already match the new site (ink #0B1620, cyan-500 #00B8D4). Never key
 * this file on a theme's token names again: the theme can rename them and the
 * plugin would not know. Every var() carries the tokens.css value as its
 * fallback so the card renders the same if tokens.css ever fails to load.
 *
 * CONTRAST (measured against the card surface #142231):
 *   fg-1 #EAF1F8 body/title ........ ~14:1
 *   fg-2 #B8C5D2 secondary text .... ~9:1
 *   cyan #00B8D4 links ............. 6.8:1
 *   danger #FF572D error text ...... 5.1:1
 *   control border #657D96 ......... 3.8:1 (SC 1.4.11, 3:1 floor)
 *   button: #062029 on #00B8D4 ..... ~8:1
 *
 * SPECIFICITY: every descendant rule is `.oae-waitlist .oae-waitlist__foo`
 * (0,2,0) on purpose. The host page can carry (0,1,1) rules against bare
 * inputs (tokens.css `[class*=" oae-"] input`, a theme's `input[type=email]`),
 * and a bare single-class rule loses to both. Do not "simplify" them.
