Hall of Fame Display IntersectionObserver Audit: Pause Offscreen Athlete Videos Without Surprise Playback
A school hall of fame kiosk in the gymnasium lobby or athletic hallway often presents inductee profiles as a scrollable list — portrait photograph, name, graduation year, sport, and a short interview video recorded at induction night. When a visitor scrolls through that list, the videos for profiles that leave the viewport should stop playing. When they do not stop, the result is several interviews competing for the lobby’s audio system at the same time, a visitor who did not choose to start the playback, and a display that broadcasts audio from profiles no one is looking at. The symptom is common on media-heavy recognition kiosks and the cause is almost always the same: the platform uses IntersectionObserver to detect when a profile enters the viewport, but the corresponding pause logic for profiles that leave is either incomplete or written against assumptions the API does not support.

School Hall of Fame ResizeObserver Loop Triage: Keep Profile Layouts Stable
A school hall of fame display in the gymnasium lobby or athletic hallway holds something irreplaceable: the visual record of every athlete the program has chosen to honor. Each inductee profile on the screen carries a portrait photograph, name, graduation year, sport, and award tier. When that grid is built with a ResizeObserver — a browser API that reports changes to an element’s dimensions — the platform can respond gracefully as the display rotates between portrait cards or adjusts from landscape to portrait when a kiosk orientation changes. Used carefully, ResizeObserver is the right tool. Used carelessly, it triggers a feedback loop that fills every frame with layout recalculations and surfaces a browser error that does not explain itself: ResizeObserver loop completed with undelivered notifications.
