/* SolveXI company site · 2026-10 direction (spec: site/REDESIGN.md, tokens recorded in ../DESIGN.md)
   Near black ground with a faint 64px hairline grid, lime accent, Inter Tight headlines,
   IBM Plex Mono uppercase labels, rounded dark panels with 1px hairlines, no shadows.
   Motion: every initial (hidden) state lives inside `prefers-reduced-motion: no-preference`
   and behind `html.js`, so reduced motion and no JS both show the end state.
   v3 (2026-10-17, spec: site/SITE_V3.md): shared by index.html, sample.html and technology.html
   (replay.html may reuse the chrome). New components sit in the "v3" block below the footer rules. */
