/* System Edition panel — step 1 UI prototype (stub data).
   Cyberpunk / sci-fi blue theme: deep-space navy base, neon cyan-blue accents,
   neon magenta for magic, soft glows. Layers on the game-flavored pieces:
   level/exp, five-dim radar, growing forest, 「叮！」.
   Columns are equal-height: the forest fills the left column so both columns
   align at the bottom (no protruding block). */
