/* =========================================================================
   Header redesign (REQ-202609211213) — single-row header, logo lockup with
   legibility scrim/shadow, translucent gradient bar, mega-menu dropdowns
   for Contractor Services / IDS / Project Spotlight. Replaces the old
   two-row .home-header / .home-nav-* header markup on every page.

   Kept as its own file rather than appended into the existing site.css
   (5,946 lines) — that file's old .home-header/.home-nav-* rules become
   unused once this markup ships (left in place there as harmless dead
   code — a non-blocking cleanup follow-up, not risking a blind edit
   across the ~15 separate media-query blocks that reference them there).
   This file is loaded after site.css on every page, so the one override
   below (.home-shell) wins on the cascade without editing that file.
   All other selectors here are new class names, checked against the full
   site.css for collisions before use (.site-header already existed there
   as unrelated leftover CSS with a box-shadow rule, so this header is
   namespaced .icr-header-bar instead, avoiding that collision). ========= */

/* =========================================================================
   Historical & Digital Preservation real hero photo (REQ-202609211213,
   Castillo decision 2026-09-22): site.css's .historical-hero rule (line
   ~2382 of that 5,946-line file) still points at the generic shared
   stand-in "Artboard 3-100.jpg" used across all 6 drone-service hero
   sections. Overriding it here — this file loads after site.css on every
   page, so this wins the cascade at equal specificity — rather than
   editing that large shared file directly for one line, same reasoning
   the file's own header comment above gives for the .home-shell override.
   Replaces the borrowed Historical Restoration stand-in with the real
   Canva-generated photo (public/assets/Images/historical-digital-preservation-hero-ai.jpg),
   already committed. This selector only ever matches
   historical-digital-preservation.html — no other page uses
   .historical-hero — so there is no risk of this bleeding onto another
   page's hero. ========================================================= */
