The critic, round 1

This is a real idea, not a reskin. A live airflow solver draws the pictures as technical plates, and it runs through every scene: the hero room, the pinned "revizie" stepper with an honest 56→100% readout, the drag-to-clean filter, the wind-tunnel loader and the footer lockup in wind. The palette is used with discipline, keeping to brand blue and red, paper and navy. Next to naked-city-films it falls short in three places. The hero headline is small and sits inside a small card over a busy field of eddies that reads as noise rather than a room. The services plates are dim line art on navy that nearly disappears. The display type rarely reaches NKD's poster scale. The test found no errors, but no navigation strips were captured, so the route curtain and phone menu can't be checked, and only the home page was tested.

• The airflow engine as art direction: draughtsman-style plates with hatching, coil fins and streamlines, colour meaning temperature. It's specific to HVAC and avoids stock photos, as the brief asked.
• Pinned 'O revizie, pas cu pas' stepper. One cutaway unit goes through six states and the airflow readout climbs 56% → 79% → 94% → 100%. It is the strongest trust-building moment on the page and reads clearly frame by frame.
• Loader: the logo stars sit in a blue wind tunnel with streaklines bending around them. It's a branded opening that ties the logo to the theme.
