Tentative next-up for bracket matches waiting on live courts; per-court score keeper QR codes

Matches whose opponent comes from a live match now show in the queue and under
courts as 'X vs winner on Court 2 · ready ~time', which is what double
elimination needed. Score keeper access is a QR per court on the desk plus a
printable page; the copy-link button is gone. Release 0.4.1.

 ## [Unreleased]
 
+## [0.4.1] - 2026-09-03
+
+### Added
+- Bracket matches that are waiting on a live match now appear in the queue and under each
+  court as "Net Gains vs winner on Court 2 · ready ~2:33", so double elimination and late
+  single elimination rounds still show a next-up time. These are tentative (no on-deck
+  alert until both teams are known).
+- Score keeper access is a QR code per court, shown on each court card of the desk, plus a
+  printable page with all courts' codes (`/admin/t/<slug>/keeper-qr`). The copy-link button
+  is gone; "Open on this device" remains for the organizer's own phone.
+- Idle courts show their next-up match too.
+
+## [0.4.0] - 2026-09-03
+
+### Added
+- **Courtside Manager**, a score keeper page per court (`/keeper/<slug>/<court>?k=…`). Big
+  +/− buttons, undo, sets for best-of-3, and a Finalize step with confirmation that appears
+  once a side has won under the tournament's rules. It follows whatever match is on the court
+  and moves to the next one automatically. The link is opened or copied from the court card
+  on the desk; it can only score and finalize, never edit a finished result.
+- Court cards on the public board show the estimated finish time of the current match.
+
+### Changed
+- Organizer desk: the Phase section now sits below Courts and Queue, so the score pads
+  are at the top during play.
+- Multi-set running scores (`liveSets`) show on the public board while a keeper is scoring.
+- Match durations outside 2–90 minutes are ignored for the ETA average.
+
+## [0.3.1] - 2026-09-03
+
+### Added
+- Every team name on the public board (courts, up-next, bracket tree and list, pool
+  standings, team schedules) links to that team's page at `/t/<slug>/teams/<id>`, which
+  shows their next match, court, record and schedule. Team pages by private code still work.
+- Court cards show the running average game time and minutes played, and a "Next up" line
+  with the match predicted for that court and the clock time it should be ready.
+- Up-next queue shows the expected clock time as well as minutes.
+- Footer links to the organizer desk.
+
+### Fixed
+- A team's schedule on its page shows scores from that team's point of view.
+

+## Score keepers (Courtside Manager)
+
+You don't have to score every court yourself. Each court card on the desk shows a **score keeper QR code**; "Score keeper QR codes" at the top of the desk prints one large code per court to tape at the scorer's table. Whoever is sitting at that court scans it and gets Courtside Manager, a full-screen page with two big + buttons, a − for a mis-tap, Undo, and a Finalize button that appears once a side has won the set under your rules. The page always shows whatever match is on that court and switches to the next one by itself when the previous is finalized, so one link lasts the whole day.
+
+A keeper link can only do two things: update the running score of the live match on its court, and finalize it. It cannot change a finished score, forfeit, or touch anything else; corrections are made from the desk ("All matches"). Links are signed with the server's `SESSION_SECRET`, so if that changes the old links stop working and you copy new ones.
