Surrounding screens refresh: live hero, row-style match cards, form bars, unified bracket

Design handoff steps 4-5:
- LivePage: headline live-match hero (gradient card, live ring, smallcaps
  stage/venue + minute, big mono score, 3-segment in-play win-prob bar);
  favorite team's live match takes the hero slot
- MatchCard: played matches as stacked team rows with the beaten side
  dimmed; scheduled matches as a centered 'vs' pairing (model hint and
  venue stay)
- GroupTable: Form column — tiny W/D/L bars (accent/gold/loss) computed
  from finished group matches
- BracketPage: one round-selector layout on every screen size (cards in
  a 2-col grid, losers dimmed), gold 'Projected champion' banner on the
  Final view; what-if mode, advance bars, R32 and the third-place
  play-off all unchanged
- Predict title race: leader bar, rank and percentage in gold
