   SignalMatrix AI — Global stylesheet
   Reusable across every page: reset, layout primitives (container,
   section, eyebrow, h2, btn), the header/nav, the trust bar, and the
   footer. Load this on every page, after colors-and-type.css and
   before the page's own stylesheet.

   Anything page-specific (hero, stat cards, FAQ, forms, etc.) does NOT
   belong here — it lives in that page's own <page>/style.css instead,
   so this file stays safe to share unmodified across the whole site.

/* Mega menu — opens toward the bottom-right, anchored to its own
   trigger's left edge. Verified to fit within the viewport from 1025px
   up at the current column count/width; re-check with mega-check2.js in
   the scratchpad tooling if columns are added. Visibility is driven by
   JS (.is-open, with a hover-intent close delay — see global.js) rather
   than a plain :hover selector: a far column can sit well away from the
   trigger, and :hover drops the instant the pointer leaves the box
   mid-transit, which a delay absorbs but an instant CSS hide can't.
   :focus-within stays CSS-only since keyboard focus has no such gap. */
