Startup builds one settled output reserve before DeckLink scheduled playback starts: the completed-frame reserve must reach the configured depth and remain ready for the configured settle window. When DeckLink input is available, startup also waits briefly for three ready input frames before the render thread starts so the first render ticks are deliberate rather than lucky.

Startup order is:
1. start render thread
2. build a settled completed-frame output reserve at normal render cadence
2. build a bounded completed-frame output preroll reserve at normal render cadence
3. try to attach DeckLink output
4. start telemetry and HTTP either way
