description: >-
  Surface lineup correlation analysis (QB-WR stack contribution, opposing-RB anti-correlation,
  lineup-level boom/bust) in a new Matchup Analyzer view or tab, consuming the already-built
  correlation simulation infrastructure.

Add a "Matchup Analyzer" view (or tab within the existing matchup page) that surfaces lineup correlation analysis for the week's head-to-head matchup. The simulation infrastructure to compute correlations is already built and unsurfaced in the UI.

## Existing infrastructure

- `player_pair_correlations`, `player_variance`, `player_archetypes` DB tables.
- Cholesky-decomposition correlated Monte Carlo in `libs-server/simulation/` and `libs-shared/simulation/`.
- Completed task references: `task/league/build-player-correlation-simulation-system.md`, `task/league/implement-league-wide-correlation-simulation.md`, `task/league/enhance-simulation-with-market-data-and-game-correlations.md`.

## Surface ideas

- QB-WR same-team stack contribution to win probability.
- Opposing-RB anti-correlation impact on the matchup.
- Lineup-level boom/bust distribution and correlated upside/downside.
- Win-probability decomposition by player pair.
