/* ═══════════════════════════════════════════════════
   SYNTHETIX ARCH  v4  — Miguel González Portfolio
   KEY FIXES:
   · Hero elements start VISIBLE (JS sets opacity:0 then
     transitions to 1 — never depends on CSS forwards fill)
   · Canvas z-index:0, hero content z-index:2 — no occlusion
   · Chatbox panel uses position:fixed, not absolute
   · Responsive: 4 breakpoints 1200/960/600/380px
   · Material Symbols for edu & chatbox icons
