/*
 * =========================================================
 * OLYTIC SOLUTIONS - On-Site Visit Page Styles
 * onsite.css  /  Route: /onsite
 *
 * A distinct, high-intent page for the complimentary on-site
 * visit (a half-day, in person). Compact dark hero, a numbered
 * "what the day looks like" timeline, an outcomes strip, and a
 * single considered request panel. Posts to the same intake
 * endpoint as /contact and /sessions.
 *
 * Self-contained: carries its own hero, timeline, panel, and
 * the shared .f-* form primitives (same language as contact.css
 * and sessions.css), so it does not depend on sessions.css.
 *
 * Requires: tokens.css, typography.css, buttons.css,
 *           nav.css, footer.css, layout.css
 * =========================================================
