Select sky beneath an obstructed top border
Select sky beneath an obstructed top border ## Problem `sky_mask_low` (`crates/algo/src/segment/sky.rs`) seeded sky growth only from the top 1/40th of the image. When fewer than 5% of those pixels were likely sky (overhanging trees, an archway, a bridge, a ceiling), it returned `None` and selected no sky at all, even with sky visible lower in the frame. ## Change - When the top-border seeds are sparse (< 5% of the band), clear them and look for high-confidence sky (`score > threshold + 0.1`) in the upper half of the image, as 4-connected components. - Each component must cover at least 0.5% of the image and at least 16 working-resolu
