/* ── Danu Strategy — AI Assistants landing page ──
   Page-specific stylesheet for /ai-assistants/. It now uses the same fonts
   as the rest of the site (Lora headings + DM Sans body/labels) and pulls
   the brand palette + nav + footer + hamburger drawer from /assets/base.css
   (imported below and shared with /assets/site.css), so type, chrome, and
   colors can't drift. What stays page-specific is only this page's own
   components (message thread, connector diagram, use tiles, case cards,
   process rail, testimonials) and its type scale.
   Gold used as TEXT uses the darkened --flag-ink (WCAG AA on paper);
   the lighter --flag is kept for decorative strokes/borders only. */
