/* ============================================================
   MWINDA DIGITAL — tech skin
   One layer over the existing stylesheets (styles.css, bi.css, os.html),
   loaded after them. It changes how the platform looks, never what it does:
   no markup the scripts depend on is touched, and deleting this file returns
   the platform to its previous look intact.

   The system, in one line each:
     · Gold is the brand — the logo, primary actions, emphasis.
     · Electric blue is the machine — labels, readouts, HUD lines, focus.
     · Orbitron for display, Exo 2 for reading, JetBrains Mono for data.
       Every glyph reads as tech; long French paragraphs stay readable,
       because the body face was designed for text, not for headlines.
     · Effects are static where they can be and transform-only where they
       move — a low-end Android should not pay for the look.
   ============================================================ */
