/* =========================================================
   Conflict Casualties — product theme
   Layered over styles.css. Every rule is scoped to html.rd, so only
   pages that opt in (currently index.html) change.

   System
   - One brand colour: graphite ink. On a page about two peoples'
     dead, any saturated UI hue risks reading as a side; colour is
     reserved for the data (olive = Palestinian, navy = Israeli).
   - Soft surfaces: white cards on a cool grey page, 24px radius,
     shadow instead of rules.
   - Pills for every control; badges for labels and status.
   - Frosted sticky chrome. Subtle lift on hover, press on active.
   - Full dark theme; motion removed under reduced-motion.
   - Casualty figures are never animated.
   ========================================================= */
