Replaces the hardcoded 2026 Men's region structure with a per-event
configurable system so the same ncaa_68 template works for Women's
March Madness (different region names and play-in placements each year).
- Add `bracket_region_config jsonb` column to `scoring_events`
- Export `ALL_16_SEEDS` and `BracketRegion`/`BracketPlayIn` interfaces
from bracket-templates.ts so both server and client share the type
- Admin bracket entry form now shows a "Configure Regions" section:
editable region names + add/remove play-in seed selectors (ShadCN
Select) per region; slot map updates live as config changes
- Server action parses region config from form, validates total = 68,
stores it on the event, and passes it to bracket generation
- `advanceFirstFourWinner` reads stored `bracketRegionConfig` from the
event row first, falls back to template.regions for existing events
- Fix opponentSeed formula (was `seedNum <= 8 ? 17-n : n`, always `17-n`)
- Remove duplicate ALL_SEEDS inline definitions (now a shared constant)

* fix: use hidden input for UTC date value in add-game form
The onSubmit handler was setting the datetime-local input's value to an
ISO UTC string (e.g. "2026-03-11T17:00:00.000Z"). datetime-local inputs
only accept the format "YYYY-MM-DDTHH:MM" — values with a 'Z' timezone
suffix are invalid and the browser silently clears the field to "". This
caused the form to submit an empty scheduledAt, which the server treated
as null, so games were always saved without a date.
Fix by keeping the datetime-local input for user interaction (renamed
scheduledAtLocal, not submitted) and writing the converted UTC ISO string
into a separate hidden input named scheduledAt in the onSubmit handler.
Also adds app/lib/date-utils.ts with a localDateTimeToUtcIso helper and
matching tests to document and verify the datetime-local ↔ ISO conversion
behaviour.

* refactor: use localDateTimeToUtcIso in component and clean up tests
- Import and call localDateTimeToUtcIso in the add-game onSubmit handler
instead of duplicating the conversion inline; also applies the null/
invalid-date safety from the utility to the component
- Remove the redundant "incompatible with datetime-local" test case (its
intent is better expressed as a code comment than a test assertion)
- Move the datetime-local incompatibility explanation into a NOTE comment
on the utility function's JSDoc

- Convert datetime-local input value to UTC ISO string on form submit
so server correctly parses local time instead of treating it as UTC
- Show local timezone abbreviation (e.g. PDT) in the field label
- Hoist timezone abbreviation computation out of the matches render loop

* Add playoff match games and odds storage
Introduces two new tables for bracket matchup detail storage:
- `playoff_match_games`: tracks individual game schedules within a
series matchup (game number, scheduledAt, status, per-game scores,
winner). Supports scheduled/complete/postponed status enum.
- `playoff_match_odds`: stores moneyline odds per participant per
matchup (single upsert record, no isLatest complexity).
Includes:
- Drizzle schema + relations with CASCADE deletes from playoff_matches
- Migration 0040_fat_puma.sql
- playoff-match-game.ts model with pure helpers: computeSeriesScore,
isSeriesComplete, getSeriesLeader — plus full CRUD
- playoff-match-odds.ts model with pure helpers: americanToImpliedProbability,
impliedProbabilityToAmerican, normalizeOdds — plus upsert/read/delete
- findPlayoffMatchesByEventId and findPlayoffMatchById updated to
include games and odds in their query results
- Bracket server route: add-game, update-game, delete-game,
upsert-odds, delete-odds actions
- Bracket admin UI: expandable per-match panel for game schedule
management and moneyline odds entry
- 41 new unit tests (18 game + 23 odds), all 810 tests passing
https://claude.ai/code/session_01Twt3D1bsEK3eXUhMaz6ee7
* Code review fixes: type safety, abstraction, and React correctness
- Derive PlayoffMatchGameStatus from schema enum instead of hardcoding
the string union, eliminating the duplicate source of truth
- updateGame now returns PlayoffMatchGame | undefined to reflect reality
when no row matches the ID
- Remove TOCTOU check-then-act in update-game action: call updateGame
directly and check the return value instead of a pre-flight findGameById
- Add status enum validation before the cast in update-game action
- Move impliedProbability computation inside upsertMatchOdds so callers
only provide moneylineOdds; the model owns the derivation
- Remove unnecessary dynamic import of americanToImpliedProbability in
the upsert-odds action (was already imported from the same module)
- Fix React list reconciliation bug: replace bare <> fragment with
<Fragment key={match.id}> so React can correctly track rows

Every route now exports a meta function so the browser title bar reflects
the current page. Static pages use fixed titles; dynamic pages pull names
from loader data with a sensible fallback (e.g. league name, sport season
name, team name).
Titles follow the pattern "Page Name - Brackt" for user-facing routes and
"Page Name - Brackt Admin" for admin routes.
