/* ============================================================================
   PALARID UI — design overhaul layer  (v1, Pass 1)
   ----------------------------------------------------------------------------
   Loaded LAST so it cascades over the 18 legacy inline <style> blocks without
   requiring a risky rewrite of a 2.4 MB single-file app. Every rule here is
   deliberate and traceable to the design audit.

   Direction: "calm instrument panel" — one accent, no gradient text, neutral
   surfaces, strict type/space scale, chrome recedes and content leads.

   Pass 1 scope (this file):
     A. Tokens (single source of truth) + real light theme
     B. Typography scale, flat page titles, sentence-case sizing
     C. Single accent; gradient text removed
     E. Layout: kill the 62px dead band, tighten max-width + rhythm
     G. Chrome: one FAB, calmer overlays
     + Accessibility: visible focus, 44px targets, contrast-safe borders
