* fix(web-player): buffered widget swap + solo-board hold to end directory-board black flicker A fullscreen widget (e.g. a solo directory board) re-rendered on the advance timer: renderContent tore the container down to black (innerHTML='') BEFORE the replacement iframe finished loading, and a single/only-active widget re-advanced to itself every duration_sec — so the board cycled black every few seconds. That reload was ALSO the only thing refreshing the board's static, server-rendered data, so simply holding it in place would freeze the data. - Buffered swap: build the new widget iframe hidden OVER the current content and reveal it on 'load', then tear down the outgoing content — no black frame on any widget transition. On a load timeout, keep the last-good board and discard the dead hidden frame via a shared cleanup path (don't reveal a blank frame); a transient server blip self-heals on the next refresh. - Solo/held widget (nextActiveIndex === currentIndex): hold in place and refresh its DATA on a decoupled interval (WIDGET_SOLO_REFRESH_MS = 60s) via the buffered swap, instead of re-querying the DB + re-rendering full HTML every duration_sec, fleet-wide. Scoped to non-wall fullscreen widgets; wall+widget keeps the legacy path.

Delete the duplicate loop entirely and advance via nextItem in both the held (WIDGET_SOLO_REFRESH_MS cadence) and rotating (duration) cases: nextItem re-evaluates the schedule every cycle and re-renders the held board through the buffered swap (still no flash), and drops the duplicate code path that caused the bug. Verified: the timer-lifecycle harness (6 scenarios / 68 assertions) still passes, including widget->video transition and the leak/timer-count checks.
