Give product screenshots a painterly atmospheric stage

Float each screenshot over an ambient wash painted from its own colours (a tiny
blurred thumbnail), layered with the aurora, a designed green->teal gradient,
and fine film grain — the "based on our real product screenshot" treatment.
- ui/art-stage: reusable atmospheric stage (ambient LQIP + aurora + grain + a
  floating shot with depth)
- hero + bento: swap the flat frames for ArtStage
- public/images/ambient: per-screenshot colour-wash thumbnails (<250B each)
- remove the now-unused media-frame

e2e green (12 passed).
