/* ============================================================
   Datacator — THE INSTRUMENT PANEL (v4, 2026-07-24)

   THESIS: owners are flying blind; instruments exist so you don't.
   The page alternates handbook pages (warm white, line-work, plain
   warm copy) and panel moments (navy, where instruments live).
   Refuses: card grids, eyebrow grammar, section numbers, mono
   costume, scattered entrance effects.
   OWN-WORLD: Brand Guidelines V1 palette/type, engraved bezels,
   graduation rings, two-tone needles, dotted checklist leaders,
   plotted course line-work.
   STORY: your questions → the checks you've tried → the instrument
   → one clear view (proof) → what you get → talk to us.
   FIRST VIEWPORT: directional gyro settling above the tagline,
   legal line at base; single action = scroll.
   FORM: grounded direction #4 (instrument panel), seed 7a165af8.

   All copy comes from content.js. Brand Guidelines V1 binding.
