/* =====================================================================
   Tabotec — public site styles
   Redesign rolled in from approved v3 mockup.

   Direction:
     · Palette sampled directly from the logo: midnight navy #102030 +
       signal cyan #50e0e0.
     · Inter for both display and body (heavy weights + tight tracking
       carry the display effect). No serif. No italics.
     · JetBrains Mono for instrumentation micro-labels.
     · Square (4 px) buttons, deep navy primary → cyan-deep on hover.
     · Asymmetric numbered tile grid, with optional inverted dark tile.
     · Dark navy footer with an ambient TABOTEC wordmark stamp.

   Class names are kept compatible with the existing HTML where possible
   so the per-page edits stay small.
