/* MoonBite design system: the component kit shared by the homepage and every
   redesigned inner page. Built to docs/moonbite-guidelines.html.
   Every class is ds- prefixed so it never collides with the legacy mb-* layer.
   Put class="ds" on the page's outermost content element.

   d03 Void/Bone carry it, Moongold on ~5% of a screen, red/green as data only.
   d04 display face twice per page (wordmark in the header + .ds-title);
       every number, hash, address and height in mono with tabular figures.
   d06 one easing, durations 120 / 240 / 600 ms, reduced motion respected.
   d14 radius 6 controls / 10 cards / 20 tiles; spacing 4..96;
       one gold action per view (.ds-btn.gold), everything else ghost.
   d15 content max-width 1140; no modal, no countdown. d17 4.5:1 text. */
