/* Safemii website — single shared stylesheet (the ONE brand system).
   Brand colors/tokens mirror the app (SafemiiTheme.kt + DesignTokens.kt) and the
   mark in branding/safemii-icon.svg. Every page links this file; no page defines

   Design system: 8pt spacing grid + modular type scale + restrained color
   (headlines are near-black, indigo is an accent only). Calm, premium, uncrowded.
