/* Reflect Optics and Dr Raycho Andreev, Plovdiv.
   The trial lens of the practice's own trial frame: clinic steel and white, the black of the lens case,
   the red of the trial-lens rims and the turquoise cloth of the optician's photos. Light is the clinic,
   dark the darkened examination room. Every colour is a custom property; theme.js sets data-theme, and
   without it the system setting decides. */
