   devices/ring-lab · every section under the bar

   Measure at 1440: section label 14/500, display 64 and 48 at 500
   with -0.03em, body 16/24 in an 822 measure, counter 180, carousel cards 427,
   feature cards 382, marquee slides 400 by 560. Type is Phenome's Helvetica,
   colour is Phenome's navy and ink, and the accent is
   a cool brand blue. Copy rule: no dashes, no all caps.

   Motion states that hide content are scoped to `.lab-js`, which lab.js adds,
   so a page whose script does not run is simply the finished page.
