Land Back on the opened card (clear of header/nav); card spacing

- Feed remembers the opened card (ui.feedAnchor) and, on Back, scrolls that
  exact card just below the sticky header via scrollIntoView + a computed
  scroll-margin-top; re-corrects on webfont load and as off-screen cards
  render their real height, but yields once the user scrolls
- history.scrollRestoration = 'manual' so the browser doesn't fight it;
  per-session scroll memory cleared on cold launch
- Cards: ghost number nudged off the top edge; sprite dropped 10px (flex
  column grows the card, so nothing overlaps); intrinsic size bumped to match
