/* ==========================================================================
   DeilTech — Development detail page template
   Scoped to the hero-only page layout (ViewData["HeroLayout"] = true).
   This is the SHARED stylesheet for every individual Development detail
   page (Strathmore Hub is the first; iTex Flex Park, Affordable Housing,
   Advocate Building, and future developments reuse it as-is). A future
   page should only need its own hero photograph, copy, and fact/gallery
   content — not new CSS — to slot into this template.

   Reuses the bronze / charcoal / white tokens and .dt-section / .dt-card /
   .card-grid / .value-grid / .dev-grid / .dt-btn / .cta-band primitives
   defined in home-hero.css, home-sections.css, and components.css. Does
   not modify any of those shared files.

/* ========== Flagship photo hero ========== */
/* Built on the PageHero component's "media" variant with a real
   MediaImageSrc (see components.css .page-hero__media-image) instead of
   the placeholder gradient used by Capabilities/About. Occupies roughly
   55-65% of the initial viewport height (62vh), matching the approved
   Strathmore Hub / Capabilities hero proportions. .hero-header is
   position:absolute, so this section reserves top padding to clear it. */

     header height at short-viewport widths. The tablet override below
