   The horizontal mask carves left/right "wings": grid column reads on

   needed — the grid placement handles that structurally.
   Tuning knobs:
     · opacity (intensity)  — currently 0.5 (sits in upper register)
     · blur (literalness)   — 2.5px reads as photo, not color field
     · saturate (charge)    — 0.4 keeps it warm-light, not iconographic
