/* ═══════════════════════════════════════════════════════════════════════
   NavView — website styles

   The design language is the app's, not a web interpretation of it.
   Tokens are lifted from:
     app/src/main/java/com/navview/ui/theme/NavColors.kt   (surface + text ladders)
     app/src/main/java/com/navview/ui/theme/NavTheme.kt    (palette, alpha, spacing, type)
     app/src/main/java/com/navview/ui/theme/Theme.kt       (uniform 6dp shape)
     app/src/main/java/com/navview/ui/theme/Type.kt        (families)

   House rules carried over from the app — these are not stylistic
   preferences, they are enforced in the codebase:
     · Dark only. There is no light theme.
     · ONE radius: 6px. Everywhere.
     · No box-shadow, no blur, no glow. Depth is surface tier + hairline.
     · Dividers are gradient hairlines fading to transparent, never solid rules.
     · No coloured left rails on rows. Status is a micro label or type colour.
     · Never raw white or black text — only the three-tier text ladder.
     · Numerals are tabular and negatively tracked; labels are uppercase
       and positively tracked.
     · 44px is the touch floor. Not 48.
     · One accent (steel). Action blue is the CTA only.

   Hex literals belong ONLY in :root.
