Pure functions in src/lib/scoring implementing docs/SCORING.md: cell values (override > judge average), weighted raw totals, raw and placement points with tie averaging, and competition-ranked standings. Coverage thresholds are enforced at 100% for the module. Also silences the hydration warning caused by browser extensions modifying <html>. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Scoring rules
All implemented in src/lib/scoring/ as pure functions. Tests must cover every rule below.
1. Cell value (team × criterion)
- Direct game: the admin score row. Missing → not scored. Judge rows (e.g. left over from a mode switch) are ignored.
- Judged game:
- If an admin override row exists → use it.
- Else average of non-revoked judges' values for that cell. Missing judges are ignored (not zero).
- No judge values → not scored.
2. Team raw score for a game
raw = Σ (cellValue × criterion.weight) over scored criteria.
A team with zero scored cells is unscored for that game (not 0).
raw is rounded to 6dp before ranking so float noise from averaging can't break a real tie.
3. Game points
- raw mode:
points = round2(raw × multiplier). - placement mode: rank scored teams by raw desc. Award
placement_points[rank-1] ?? 0.- Ties: tied teams share the average of the places they span, rounded to 2dp. e.g. two teams tied for 1st with [10,7,5] → each gets 8.5; next team gets 5.
- Then × multiplier.
- Unscored teams get 0 and are not ranked.
- Only games with status
liveordonecount toward totals.upcominggames contribute nothing (prevents half-set-up games leaking).
4. Event total
total = Σ game points + Σ adjustments.points
5. Standings
Sort by total desc. Ties share rank (standard competition: 1,1,3). Tie display order: team sort_order.
Test cases to include (minimum)
- Karaoke: 5 criteria × 1–5, 3 judges, one judge missing a team → average uses 2 judges.
- Override beats judge average.
- Revoked judge excluded.
- Weights applied.
- Placement with a 2-way tie at 1st and 3 teams.
- Placement with more teams than placement_points → extra teams get 0.
- Multiplier on both modes.
- Upcoming game ignored.
- Adjustments (+ and −) added; adjustment tied to an upcoming game still counts (it's explicit).
- Standings tie → shared rank.
