- F5 on a channel page kept bouncing to the feed — the App init dropped history.state._chan
like the (intentionally non-replayed) YouTube search. Now channelView restores from _chan on
load and the stamp preserves it, so a reload stays on the channel page.
- The banner was stretched/cropped (bg-cover). Render it as an <img object-contain> with a
capped height, letterboxed on the surface colour, so its real aspect ratio is kept.
- The round avatar's top was clipped by the banner: the banner's position:relative container
painted above the static identity row. Give that row relative z-10 so the overlapping avatar
sits on top.
