/* ============================================================
   CASES.CSS — Manu Farías portfolio
   Depends on: tokens.css (must be loaded first)

   All styles for case study content injected into the drawer.
   Scoped under .case-content so they never bleed into the landing.

   Utility classes (.screen-frame, .browser-frame, blockquote)
   are also here — they only appear inside case content.

   Sections:
   1. Case content — scoped under .case-content
   2. Screen frame utilities
   3. Responsive
