/* Mootstead design tokens and the accessibility floor (VISUAL-DESIGN-SYSTEM.md).
   Ground, not glass: chalk and warm stone, peat and ink, moss and lichen, and
   one ember, used once on a screen for the instant a Moment is made.
   Hand-written in the token shape the contrast check reads: primitives and
   semantic names in the root block, the dark theme in the media query and
   again under data-theme. Light is the default; dark follows the device only.
   No closing braces inside comments in the token blocks: the reader stops at the first one. */
