Diagonal + Mirror Pairs + real inequality arrows + parity markers, together — as an actual board would present them
🟡 Diagonal: gold-outlined cells also need 1–7, no repeats.
🟠🟣 Mirror pairs: same-colored cells must match.
➤ Inequality arrows: point toward the smaller value. Double arrows mean a gap of 2+.
🟢 E/O badges: that cell must be Even or Odd.
All normal row/column rules apply throughout.
