   Technology & Intelligence — shared kit (.xt-*). Load after assets/css/brand/hub.css
   and before any page stylesheet. Markup comes from partials/tech/kit.php and
   partials/tech/next.php only; pages style their own sections with their own prefix.
   Tokens from core.css :root only; no new colours; no gradients except core mask
   fades; no !important. Works on paper, band--alt and band--ink. For an ink surface
   that is not a band (a dark card or panel), add .xt-on-ink to it.

   Pieces
   • .xt-logo / .xt-logo--word / .xt-lg            one technology mark (svg or wordmark chip)
   • .xt-stack--chips | --tiles | --logos | --row   lists of technologies; .xt-marquee wraps a row
   • .xt-ico (+ .xt-ico--mono)                      24px line icons, accent parts .a / .af
   • .xt-badge--seal | --shield | --hex | --chip    code-built standards badges; .xt-badges grid helper
   • .xt-next                                       the "Keep going" onward aid
   Size hooks: --xt-tile (tile min width), --xt-badge (badge art size), --xt-word (wordmark size).
