/* DooRod styles — "Soft modern SaaS".
   Off-white ground, one teal accent, generous rounding, shadows instead of
   heavy borders. One stylesheet, no framework, no web fonts: the app has to
   open fast on a phone in a garage, served off a Raspberry Pi.

   Two rules hold the whole thing together:
   1. Every control is sized from --control-h, so a button standing next to an
      input or a select lines up with it exactly.
   2. Controls that sit together share a size class. `.btn.small` belongs next
      to `.btn.small`, never next to a full-size button. */
