The MDOT streams use 10-second segments with only a 3-segment live playlist. The previous low-latency HLS.js settings (liveSyncDuration: 2, backBufferLength: 0) left almost no buffer ahead of playback, causing rebuffering every few seconds. Switch to stable live settings (liveSyncDurationCount: 3), restore back buffer, stagger stream startup, and avoid Safari live-edge seeking. Co-authored-by: jeremy <jeremyepowell@hotmail.com>
Fix black screen caused by unquoted stream URLs (JavaScript syntax error). Uses the same stable HLS settings as the Hwy 301 dashboard. Co-authored-by: jeremy <jeremyepowell@hotmail.com>

Summary
Fixes recurring 3–5 second buffering stalls on traffic camera dashboards and adds the Goodman Rd & Horn Lake Rd intersection page.
Root cause (buffering)
The MDOT HLS streams use 10-second segments with only ~3 segments in the live playlist (~30 seconds total). Low-latency HLS.js settings left almost no buffer ahead of playback, causing stalls every few seconds.
Root cause (black screen on Goodman dashboard)
The stream URLs were missing quotes, which is a JavaScript syntax error — the entire script fails to run:
