   Lucent · the style
   Clinical calm, layered light: Cormorant Garamond headlines with an
   italic lit phrase in mineral, Lexend for everything else, on cool
   white with frosted panels.
   Signature pieces: the cross-section (.layers: wavy layers drawn by
   lucent.js; pick one to read about it), the pause ring (.pause: the time
   between a consultation and treatment), treatment cards that give risks
   and downtime equal billing (.tx), registration chips (.reg) and frost
   (.frost).
   Motion: html.calm stills everything (footer switch, remembered as
   "site-motion"; default from prefers-reduced-motion).
