/* ============================================================
   Poise — Design System: "The Plumb Line" (second edition)
   Tokens sourced from DESIGN.md / Poise Visual Identity v2.

   REVIEW PASS — changes from the previous build:
   01  Ember de-escalated from 18 elements to 2 (hero CTA, form
       button). Eyebrows, stat numerals, walk-numbers, claim-card
       border and founder initial no longer take the action colour.
   02  Stat numerals set in Bone. Ember never paints a decline.
   04  Device tilt removed — nothing on this page is off-plumb. The
       screenshots now sit in an upright phone bezel (.phone).
   05  Inputs get a real focus ring matching the buttons.
   06  h2 raised to a genuine second step (40px); h3 unified as
       Newsreader 500 and .headline-sm retired.
   07  .walk-row--solo added for rows with no screenshot.
   09  .hero::before ember gradient deleted. Sage given the
       already-true claims. .btn-bone put to work in the hero.
   10  .moment-close set upright — italic is reserved for speech.
   12  Radius scale aligned to the guide: controls 10, cards 14,
       chips pill. Unclassed links now have a defined colour.
