/* K-LiTE website design tokens - per the approved Design & Experience Framework
   (2026-09-10). This is a website-specific palette, distinct from the amber
   #FFBF00/#FFBE00 + #333333 system used in Senthil's docx/pptx/newsletter
   templates - decided 2026-09-11 so the site can use the framework's more
   restrained black/white/amber architectural system. Variable NAMES are kept
   stable so every existing rule below re-themes automatically; only values
   changed, plus a few new tokens (night-2, ink/paper aliases, line, steel). */

/* ---------- Mega-menu (Products / Resources / Company dropdowns) ----------
   Added 2026-09-11, continuing Phase 1. Desktop: CSS-only hover/focus
   dropdown, per the framework's "open predictably, preserve stable
   geometry" rule - no JS, no layout shift. Mobile: dropdown items render
   inline (always visible once the section label is in the open nav list),
   since touch has no hover state. Only Products/Resources/Company get a
   dropdown - Projects/Applications/Knowledge stay flat links; see the
   comment in MainLayout.razor for why. */

/* Fixed 2026-09-16: items with a dropdown (Products/Resources/Company) are
   wrapped in this div, so their <a> is NOT a direct child of the flex
   .klite-nav-links row - the browser only "blockifies" flex items
   themselves, so that inner <a> stayed a plain inline element with a
   different box model/height than the flat items (Projects/Applications/
   Knowledge/Contact), which sit directly in the flex row and get
   blockified. That mismatch showed up as the top nav being out of line.
   Making this wrapper a flex row too gives its <a> the same centered,
