 * register.css — Página pública de registro multi-step
 * G1 v1.2 — refactor de register.php (Lote 17)
 *
 * Cromática:
 *   - Header gradient azul→cyan (igual que login.css por coherencia)
 *   - 4 colores de rol distintivos (Patient, Doctor, Researcher, Member):
 *     migrados a tokens canónicos. Patient (#f97316) → --color-warning;
 *     Doctor/Researcher/Member coinciden literalmente con sus tokens
 *     canónicos.
 *   - 4 hex Google brand identity en SVG inline (mantenidos en
 *     register.php, no aquí — son atributos `fill=` del SVG).
