/* ══════════════════════════════════════════════════════════════
   Runi Services dashboard — shared base stylesheet.

   Single source of truth for tokens, reset, and surface primitives
   used across every dashboard page. Each page links this file and
   keeps only its page-specific component styles.

   Token namespace is --rc-* per the runi.services design system.
   Legacy aliases (--fg-*, --bg-*, --runi-*, --font-sans, --radius-*,
   --shadow-soft) are kept as thin wrappers so existing page CSS
   continues to render during migration — new work should reference
   --rc-* directly.
