/* =====================================================================
 * oasis/signup.css  —  Signup screen only styles
 *
 * Loaded by templates/auth/signup.html AFTER auth.css + forms.css.
 * The signup screen uses the full-page section layout (header + step-bar
 * + sections + footer action bar) rather than the centered auth-card.
 *
 * Sections:
 *   1. Page-level typography (.page-title / .page-desc)
 *   2. Step indicator (.step-bar) — note: differs from .demo-steps
 *   3. Section card (.section + .section-head + .section-body)
 *   4. Field row (multi-column input layout)
 *   5. Form select (.form-select, sibling of .form-input)
 *   6. Postal / telephone split wrappers
 *   7. Toggle group + buttons (existing in forms.css, .signup tweaks)
 *   8. Selectable chips (multi / radio)
 *   9. Site (factory) card + rep-toggle + add button
 *  10. Same-as-company toggle + agreement box
 *  11. Action buttons (.btn / .btn-submit / .btn-back)
