/* ==========================================================================
   KORA Design System
   Futuristic financial-security aesthetic. No frameworks, no build step —
   plain CSS with custom properties, loaded directly by every view.

   Theming: dark is the default (no attribute needed). Light mode is a
   pure token-override block keyed on [data-theme="light"] on <html> —
   every component rule below reads a variable, never a literal color,
   so light mode never duplicates a single component rule.
