/* mega-menu.css — Tools navigation mega menu.
 *
 * Deliberately NOT Tailwind. This site has no build pipeline (no npm,
 * no bundler, no PostCSS) — every other stylesheet is hand-authored CSS
 * against the existing custom-property system in main.css. Introducing
 * Tailwind here would mean either a runtime CDN (no purge, worse
 * Lighthouse score — the opposite of what was asked for) or bolting on
 * a whole new build toolchain to redesign one menu. This file extends
 * the site's own design tokens (--p1, --text-dim, --ease, etc.) instead,
 * so it's a natural evolution of the existing system, not a second
 * styling language living next to it.
 *
 * Loaded on every page via header-chrome.js's HEAD_LINKS — one file,
 * one link, no per-page duplication.

/* NOTE: header-chrome.js stamps this element as
   class="nav-tools-panel mega" -- both classes on the SAME element.
   .mega-footer (further below) has always had `grid-column: 1 / -1` --
   a CSS Grid property, meaningless outside a grid container. That is
   the tell that this panel was designed as a 2-column GRID (rail |
   preview, footer spanning both) from the start, not flex. An earlier
   state of this rule had `display: block`, which broke rail/preview
   into stacked blocks; a previous pass "fixed" that to
   `display: flex`, which stopped the stacking but broke the footer's
   spanning instead, since flex has no concept of grid-column. The
   footer then became a cramped THIRD flex sibling, squeezing the
   preview panel down to roughly a third of its intended width --
   which is what caused a wrapped heading colliding with the
   illustration, truncated tool names, and an overlapping highlight
   card, all visible together in one screenshot. Grid is correct here:
   it matches what .mega-footer already assumed, restores the
   preview's real ~470px width, and needs no HTML changes -- grid
   auto-flow places mega-rail and mega-preview in row 1's two columns,
   then mega-footer's own grid-column: 1 / -1 drops it to row 2,
   spanning both. */
