/* ==========================================================================
   sneck - public landing page
   --------------------------------------------------------------------------
   Scoped under .landing; reuses the design tokens and button/kbd
   primitives from app.css (always loaded by the root layout). Own
   full-viewport chrome: nav, hero + two proof points, a real board
   shot, the feature strip, the closing CTA, footer. No app shell,
   no JS - the data-motion reveals ride reactive.css keyframes.

   v2 (landing rebuild): the page sells the real product - the
   query-pinned speed ruler and the dogfooded MCP server lead, the
   differentiators strip as anchored scannable rows, real screenshots
   as self-hosted assets (AssetVsn.url cache-busting). Tokens,
   elevation, radii, motion and type stay on the app.css vocabulary
   (each with its contract fallback), cards on the RAISED tier.

   THE LANDING IS BRAND, DARK BY DESIGN. The app's light theme
   (html[data-theme="light"], a localStorage user choice) stops at the
   door: the block below re-pins every COLOR token the landing
   consumes back to the dark values, so the storefront reads the same
   for every visitor. The app is the product; this page is the poster.
   ========================================================================== */

/* The poster pins dark on itself - and the page body behind it must
   not leak light around the edges (E2E pass #2, N6): the landing
   block is viewport-wide but the BODY paints the overscroll + any
   1px rounding gap, so pin the bed tokens there too while it hosts
   the landing. */
