CI / Build and push docker image (push) Successful in 1m19s
Store each player's leaderboard totals (wins, accumulated points and the latest display name) on player_rating alongside the Elo rating, updated in the same transaction as the match, so the board is a single indexed table query instead of aggregating every participation on each request. GET /api/leaderboard is now page-number paginated (page/limit) and returns the page, page count and total, plus the caller's own rank and page when authenticated; focus=me returns the caller's page directly. The migration adds the columns, backfills them from the match history (inserting rows for players from pre-Elo matches at the initial rating) and replaces the index. backfill_elo rebuilds the aggregates too. The web page opens on the page containing the signed-in player, marks their row and adds a numbered footer pager.

"""Keyset pagination tests: cursor values are restored to Python types.

Cursors are JSON, so a cursor carrying a datetime reaches the next
|

request as a string. Postgres/asyncpg rejects strings for timestamp
|
|
parameters (sqlite silently coerces them), so ``paginate`` must run the
|
|
decoded values through their model fields before building the WHERE

clause.
