/* Safety & Compliance - interface styles.

   Design rules (keep to these when adding screens):
   - Official-form look: square corners, flat surfaces, 1-2px rules, no shadows,
     no gradients, no decorative icons or emoji.
   - One accent (navy/blue). Colour is reserved for status and risk, and every
     status is also spelled out in words, never colour alone.
   - Plain language, left-aligned text, real labels above fields.
   - Large touch targets (44px) and 16px form text so phones do not zoom.
   - Strong keyboard focus (yellow + black), visible on every control. */
