/*
  ToolkitHQ visual design — instrument-panel cleanup
  Direction: precise, quiet, confident. A well-made measuring device,
  not a SaaS landing page.

  Palette:
    Light: Paper #FFFFFF, Ink #14171C, Slate #6B7280, Hairline #E2E5EA,
           Signal #2951F2, Ledger #147A52 (positive deltas only).
    Dark:  Background #0E1014, Surface #161A20, Hairline #232830,
           Ink #E8EBF0, Slate #9BA3B0, Signal #5B7CFF, Ledger #4DAD7E.

  Typography — exactly three faces, no exceptions:
    Display = Archivo (headings, brand)
    Body    = Inter (paragraphs, labels, UI)
    Numbers = IBM Plex Mono (readouts, stats, code, versions)
    Never add a fourth face. No roman or decorative fallbacks allowed.

  Motion:
    One orchestrated moment: hero readout digits roll into place on load.
    Everything else is still — border/color hover shifts only.
