/* Companion dialer — a natural extension of the Nexiloq product surface.
   Brand system mirrored from static/style.css: warm off-white ground, teal
   primary, orange accent used sparingly, Georgia serif for display, Inter for
   body, and a monospace treatment for the number itself (it is data). Light
   first, with a sober dark variant for phones used at night. */
