/* ==========================================================================
   RoboDB 2.0 — website stylesheet
   Dark theme matching the app aesthetic. Hand-written, no framework,
   no build step, no webfonts.

   Palette note: the accent is RoboDB's own indigo (the app's Run button /
   AI badge, and the same family as --accent:#4f46e5 on the existing
   /privacy /terms /release-notes pages), deliberately NOT goPanel's blue —
   the two sites should read as siblings, not clones.
