   Shared styling for project / case-study pages.
   LAYER 1 of the system: IDENTITY (tokens, nav, type, buttons, footer).
   The HERO is a swappable media slot (.hero-media holds an <img>, <video>,
   <iframe>, <canvas>, or an abstract placeholder). CONTENT MODULES below
   (.block, .dives, .gallery, .videowrap, .figure) are opt-in per page, so
   every page shares one identity but composes whatever content it has.
