/* Public entrepreneur booking.
 *
 * Deliberately self-contained: no font CDN, no icon library, no framework. This
 * page asks an entrepreneur for their name and email, so every byte it loads is
 * served from the same origin and its CSP can stay strict. The "premium" here
 * comes from spacing, type scale and restraint rather than from downloads.
 *
 * Palette is Notre Dame navy and gold, with neutrals biased slightly toward the
 * navy so greys read as chosen rather than inherited.
