/* =============================================================================
   Portfolio — Aleksander Kopydłowski
   Concept v3 — "Graphite / Ivory"
   Dwa motywy: ciemny (grafit) i jasny (kość słoniowa). Motyw wybiera skrypt
   w <head> (zapisany wybór albo ustawienie systemu) i wpisuje go do
   <html data-theme="…">, zanim strona się narysuje — bez mignięcia.

   Kolory zmienisz w dwóch blokach poniżej. Odpowiednik palety scen 3D
   znajduje się w src/hero3d.ts (stała PALETTES).
