/* Postie · tokens/shape.css — 12 / 16 / pill, crisp machined edges.
   Rows and tiles 12 · panels and cards 16 · every button, chip, pebble and input is a pill.
   The signature shape is the pebble (a rounded disc — the account-pebble, the avatar); the
   carrier-pigeon wing-arc mark is NOT rendered (type carries the mark until one exists).
   `edge` is the ONLY visible UI border: 1.5px, in --postie-edge on the working ground (text
   inputs, the reply well, the dashed AddSlot) and --postie-muted-brand for the ghost button on
   the chrome. The oxblood fill has no edge on any ground. Nothing casts a shadow. Nothing glows.
   Decoration: on a large surface the brand ground frames a working card (the quadrant pattern —
   landing hero, ProductPreview); on a small surface (390px phone, 600px email) no empty quadrant
   exists, so the charcoal becomes a masthead band and the body sits on clean ground below.
   All four tokens are the working set's, unchanged. */
