+Thin letterbox detection compares both edges against lit interior histogram samples and requires a consistently dark upper edge for at least two seconds. Histogram probes cannot determine the exact bar height or guarantee detection on every scene.
+
+Histogram capture defaults to 50 ms. The Receiver panel provides a saved Capture interval (ms) setting from 25 to 1000 in steps of 25. Existing settings without this field use 50 ms. PicCap capture timing is unchanged.

Live measurements showed raw [13,14,7] causing residual [1,1,0] to [2,2,1] at the bottom-right LEDs with the previous cutoff. Regression coverage now includes this sample.

Preserve the existing dark-scene rejection, wide-bar rule and two-second stability gate. Regression tests include live G4 measurements, one-sided and isolated dark edges, dim frames and insufficient contrast. This is a histogram heuristic; it does not measure exact bar heights.

+Default histogram capture to 50 ms and expose a persisted Capture interval (ms) in the Receiver panel (25–1000, steps of 25). Remote highlighting leaves the keyboard closed; OK opens editing. A 25 ms scheduler keeps network processing responsive independently of slower capture settings. Missing legacy values default to 50 ms. PicCap timing is unchanged. Native tests check persistence, legacy defaults and invalid values.
