/* ==========================================================================
   Nagrik Sahayak — design system  (assets/theme.css)
   Loaded by EVERY page: public/*.html and admin/*.php.

   Direction: an Indian public-service portal that is genuinely pleasant to
   use. White surfaces, one violet accent, near-black text, hairline borders,
   a single soft elevation step. The reference points are Microsoft Fluent
   and Google Material 3 at their most restrained — confident and quiet.

   No navy slabs, no cream "document" tones, no gradients on chrome, no
   glass, no neon, no emoji, no icon font, no CSS framework.

   Contents
     1  Tokens — violet ramp, neutral ramp, semantics, scale
     2  Dark theme (html[data-theme="dark"] + prefers-color-scheme)
     3  Reset and base elements
     4  Focus
     5  Native form controls (select chevron, file button, check, radio, range)
     6  Layout primitives (container, stack, grid, app shell)
     7  Components — card, button, field, table, badge, stat, tabs,
        timeline, modal, empty state, skeleton, toast
     8  Chrome — theme toggle, hamburger, tricolour strip
     9  Motion
    10  Print / poster
