/* ============================================================
   portfolio.eddiequinn.xyz — site-specific stylesheet
   ------------------------------------------------------------
   Direction: Weyland-Yutani chrome. Engineered sans, clinical
   dark, hazard amber as the working accent. The red // mark is
   the launcher handshake and appears in the header ONLY.

   This file is the site-specific layer of the relic design
   system. The shared base (reset, dark theme tokens, page
   frame, footer) lives in /shared/base.css. The shared header
   (// mark, name, handle, subhead, nav, glitch) lives in
   /shared/header.css. This file overrides only what makes
   the portfolio distinct.

   Restraint rules:
     - amber accent, max 4 uses:
         1. interactive hover/focus
         2. section rule + label tick
         3. project date / metadata highlights
         4. inline code
     - red is reserved for the // brand mark. Nowhere else.
     - no gradients, no glow, no ornament
     - one animation: caret blink.
   ============================================================ */
