   Optometrists and eyewear: Prata for headlines, Wix Madefor Text for
   reading, PT Mono for prices, prescriptions and dates, on clear-view
   paper with ink, one tortoiseshell rust and lens-glass blue for fills.
   Signature pieces: the eye test booker (.eyetest: is it covered, and
   when), the glasses builder (.specs: frame, lenses, coatings and the
   health fund gap), the frame finder (.frames: shape, size, material and
   price that really filter), and the urgent guide (.urgent: what needs
   care today).
   Motion: html.calm stills everything (footer switch, remembered as
   "site-motion"; default from prefers-reduced-motion).
