/*
  Faithful Stays v2 — Design System
  app/static/css/app.css

  Token decisions:
  - Palette matches the Faithful Stays logo: silver/brushed-metallic grayscale.
    All three themes use cool silvers, soft charcoals, and near-black ink.
    No color accents, no pastels, no gradients, no shadows. (Std #8)
  - Single accent: silver-gray. Reserved for active-nav indicators and brand marks.
  - 3px border-radius. Rounds only enough to prevent the "box is a button" ambiguity
    without introducing pill shapes.
  - No drop shadows. Hierarchy via background tone + border only.
  - No gradients anywhere.
  - System font stack: Inter loaded via Google Fonts in base.html; falls back to
    -apple-system / system-ui.
