/* Ring Virtual Try-On — Try On button, modal, video stage, mobile layout. */

/* Try On — visually paired with Add to Cart: same height, uppercase, no
   radius, no border, white text, flush right against the cart button.
   Uses a darker teal as a secondary action so the two buttons are
   distinguishable while staying in the same color family. */
