Renders showed the page background (a one-frame black flash) right before a cut when a video clip's source media was a hair shorter than its data-duration slot — the common case, since `ffmpeg -t 1.45` emits 43 frames = 1.433s at 30fps. The frame lookup only held the last frame at the exact clip end, so the sub-frame remainder rendered blank. - Hold the last extracted frame for the rest of the slot once the source is exhausted, within a tolerance floored at the compiler's 0.05s clamp epsilon so the seam is covered at any fps (2 frames alone is < 0.05s above 40fps). Clips deliberately much shorter than their slot still blank for the tail (unchanged). - Warn when the compiler clamps a video's data-duration down to its media length (slot longer than source by more than the clamp epsilon): a render-time `[compile]` warning in the producer, plus a matching `validate` warning that reads each <video>'s live duration in headless Chrome (static HTML lint can't see media durations). A shared `analyzeClipMediaFit` keeps both on one threshold. Adds engine unit tests for the hold behavior and the analyzer.
