Summary of Behavior

AceTracker is a tennis "live match intelligence" dashboard that fetches a hard-coded JSON file (mohansaksham_26171_14904082_sm985.json) and renders it as a broadcast-style scoreboard. The JSON shape is domain-specific — tournament, match, players[], score (with sets and currentGame), statistics keyed by player ID, headToHead, and liveOdds.

The UI includes:

• A pulsing red LIVE pill plus a tournament chip showing name, year, city/country, and court surface.
• A scoreboard panel with both players (name, country, ATP ranking, seed), a sets strip (each set box color-coded for the winner, with a "TB x–y" tiebreak note), and a highlighted current-game box showing points in tennis scoring (e.g. 30–40), serving player, and a red BREAK POINT callout if applicable.
• A sidebar with a "Win probability (live)" split bar, percentages, a timestamped "Last odds tick" clock, and a head-to-head summary including last-meeting tournament, date, score, and winner.
• A Match stats panel with six comparison rows (aces, winners, unforced errors, 1st-serve %, 1st-serve points won %, total points won), each rendered as a green-vs-blue ratio bar.
• A mockLiveOdds loop that jitters the win probability by ±2% every 2.8 seconds to simulate live movement.
• A dark green/glass visual palette with backdrop blur, SVG tennis-court logo, and Bebas Neue / JetBrains Mono typography.

Things That Didn't Work as Expected

• The JSON URL is hard-coded. There's no input, tab, or dropdown — you get exactly one fictional match and cannot switch players or tournaments without editing the source.
• "Live odds" aren't live. mockLiveOdds is literally Math.random() jitter around the fetched base number, so the ticking clock feels real but the data is static. That's stylish but deceptive on a screen that flashes LIVE.
• Only the first two players in players[] are ever used. Doubles matches and larger rosters would silently be ignored.
• If the JSON is reachable but malformed (e.g. missing stats[id1] or headToHead.lastMeeting), the render function throws a TypeError that bypasses the showError path, leaving the "Loading match data…" placeholder on screen.
• The set-box class toggling only supports two winners (w1 / w2) and there is no style for a set still in progress — an unwon set renders with default styling regardless.
• No refresh button. If the underlying JSON updates, the user has to reload the whole page; the only thing that animates is the fake odds jitter.
• Missing values leak through: attendance of 0 displays as "Fans 0", and a missing seeding just shows "SEED  " with nothing after it.
• The setInterval odds timer keeps running when the tab is backgrounded (no visibilitychange guard).

Prompt to Improve the App

Turn AceTracker from a one-match demo into a real-feeling live dashboard with honest data semantics. Specifically:

1. Replace the hard-coded JSON_URL with a URL bar (defaulting to the current value) plus a match-picker dropdown populated from an index JSON of available matches. Reflect the active match in ?match= so links are shareable.
2. Either make "Win probability" actually update by re-fetching the JSON on a polling interval, or rename it to "Model estimate" and drop the animated clock so the UI doesn't imply realtime data it doesn't have.
3. Wrap render() in a try/catch that routes failures through showError, and add a small "validation report" panel in dev mode that lists which JSON fields were missing.
4. Support doubles: iterate all players, render two names per side, and key stats by a side identifier instead of by player ID.
5. Add a third .set-box state for in-progress sets (dashed border, muted score) and a visible "— yet to start" for future sets.
6. Pause the odds setInterval on document.visibilityState === 'hidden' and resume on visible.
7. Hide the "Fans" and "SEED" lines entirely when those fields are absent rather than rendering blank artifacts.
8. Preserve the existing visual design — court green, yellow ball accent, pulsing LIVE pill — and keep it single-file, no external libraries beyond the Google Fonts already loaded.
