   site.css — tadkatech.in design system (Plan 361)
   ----------------------------------------------------------------------------
   Ported from sitemap/Mockups/website-redesign-dark/assets/site.css. Every page
   under website/ (except signin/, terms/, client-websites/) composes itself
   from the classes in this file. Compose, never invent: if a page needs a new visual,
   add it HERE as a reusable class rather than in a page-local <style>.

   NO COLOUR LITERAL MAY APPEAR OUTSIDE §1.
   DARK VARIANT: §1 carries the live tadkatech.in palette; §12 re-points the
   few rules that used --ink as a background or --paper as a foreground. Pages use var(--…) only.

   CONTENTS
     1  Tokens (BRIEF §1 palette, verbatim) + type / space scale
     2  Reset, base type, links, focus ring
     3  Layout — .wrap .wrap-narrow .section .hr
     4  Typography helpers — .eyebrow .sec-head .lede .serif-em
     5  Signature — .grid-bg (engineering paper)
     6  Chrome — .utilbar .nav .mega .drawer .footer
     7  Components — buttons, chips, badges, cards, stats, lists, tables…
     8  Lifecycle rail — .rail
     9  Product-screen kit — .screen and everything inside it
    10  Reveal-on-scroll
    11  Responsive (1080 / 820 / 560)
