   Chadfi IT — stylesheet (v2)
   Two themes. Light: cool white paper, deep navy ink. Dark: true-black
   OLED with a navy surface. One accent in both: lightning blue.
   Type: Manrope (display) + Inter (text).
   Art lives in .art frames, which are always dark navy so the generated
   pieces look native in both themes.
