Sports viewing layout

This route holds the grid, rails, and typography for a premium live sports experience. Use the genre tabs above for sportsbooks-style navigation (aligned with discovery patterns like Kalshi all sports ) plus full prediction-market verticals. The main column includes a live NCAA men’s scoreboard (ESPN day strip) next to the archived March bracket so you can line up games with market ladders. Rerun is the planned multimodal desk for live sports vision (frames, masks, tracks, tensors, time series) alongside that stack — see the Rerun card below. Attach a real player from your Game /live desk, a WebRTC/HLS workpad, or another origin in a new tab or iframe once you deploy outside Pages.

Client-side pull from ESPN’s public scoreboard API for the calendar day you pick — use it beside the bracket panel and market rows. Deep link with ?espnDate=YYYYMMDD (updates when you load a day).

Rerun · live multimodal desk

rerun-io/rerun logs images, tensors, point clouds, and text with a shared timeline — useful for sports pipelines that mix decode → perception → stats (for example SAM masks, homography, player tracks, or splat previews). Stream to the native or web viewer, record .rrd, or query back with the dataframe APIs. Train stays static: wire your SDK off-process, then optionally embed the viewer URL below.

GitHub rerun.io docs

01 · telemetry

uvspeed sports field

Open sports-field-ugrad from youtube-pipeline-viewer or the uvspeed web root. It publishes and applies sportsfield-telemetry / sportsfield-ball on BroadcastChannel('hexcast-stream').

02 · timeline

Rerun sidecar

Run a local Python or JS sidecar that listens to the same channel (or a WebSocket bridge), logs ball meters, players, captions, and frame timestamps into Rerun, then serves a web viewer URL via PUBLIC_RERUN_VIEWER_URL.

03 · transcript

Transcript + memo

Use youtube-pipeline-viewer for HLS, WebSocket segment telemetry, chapters, and transcript sidebar; use Train live-captions or Overview for the research memo.

Local integration runbook

Mount uvspeed assets in the pipeline viewer:

cd /Users/tref/projects/youtube-pipeline-viewer && UVSPEED_WEB=/Users/tref/dev/projects/uvspeed/web npm start

Run this Astro desk:

cd /Volumes/qbitOS/00.dev/cursor/train/train && npm run dev

Optional memo surface:

cd /Users/tref/projects/overview && npm run dev

Optional Rerun viewer:

PUBLIC_RERUN_VIEWER_URL=http://127.0.0.1:PORT/ npm run dev

Set PUBLIC_RERUN_VIEWER_URL at build time to surface an embed plus “open in new tab” (same pattern as the Broadcast desk pipeline URL).

March Madness · brackets & markets

Regional brackets (R64→E8) when JSON includes a bracket tree — 2025 is a full archive from march-arena pairings. Every game keeps id for prediction-market joins. Static data: march-seasons.json + march-bracket-2025.json. Matchup and round columns are laid out as nested cards (similar density to leerob/march-arena marcharena.com ) with ESPN-style scores like leerob/ncaam.

Bracket panel · shipped updates 1–5
  1. Full 2025 tree — four regions, R64 → R32 → S16 → E8 with scores and winners.
  2. National rounds — Final Four (ff-2025-l, ff-2025-r) + championship ( champ-2025).
  3. Region tabs — switch quadrants; horizontal scroll on narrow viewports.
  4. Seeds 1–5 strip — top chalk in each region pulled from the R64 slate.
  5. Market linkage — listing rows still use bracketGameId matching these id fields.
Extra · UX, URLs & file paths
  • Deep link — add ?tourney=2025 (or 2024, 2026) to sync the season dropdown; changing the dropdown updates the query without a full navigation.
  • Copy game id — each matchup with an id has a “Copy id” control for desks, tickets, or Kalshi/Polymarket mapping (uses the Clipboard API on HTTPS / localhost).
  • Region tab keyboard — when a region tab is focused: ← → move selection; Home / End jump to first / last region (ARIA tablist pattern).
  • Market hover — rows with bracketGameId highlight the matching card (purple ring) for quick visual join checks.
  • Source files — src/data/sports/march-seasons.json (seasons + markets); full 2025 tree in src/data/sports/march-bracket-2025.json merged at build time for the 2025 row only.

    League and club kit palettes (HEX / RGB) for lower-thirds, virtual ads, and graphics math — same idea as the bundled sports-field jersey tables in the live workpad.

    segment_anything

    Promptable masks (SAM / SAM2) for players, pitch lines, and equipment — feed tensors to stats or comp; wire inference off-process via SAM2_SERVICE_URL on your pipeline host (see Broadcast desk).

    gsplats

    3D Gaussian splats for venue / set preview (SuperSplat, mkkellogg viewer): load .splat beside the program for director rehearsal — keep GPU work off GitHub Pages.

    Broadcast desk Predictions + field viz Vision stack runs off Pages: SAM / SAM2 inference service, Segment Anything weights, SuperSplat or mkkellogg splat preview — mount via your pipeline / Game origin.

    Browser-side strip for commentary IDs, sponsor rotation, and CC — plus downstream readouts from the pitch: Gaussian splat rig, segment-anything tracks, and player / pattern classifiers (static placeholders on Train).
