fix/upload-outputs-and-hough-shape (#2)

add .env to gitignore

README: link Roboflow blog; refresh pipeline/detectors/deploy/accuracy

Verdict: any positive margin flags offside (tight tag within band); orange = level/onside-close only

three.js: 'Goal Direction' label with raised arrow; verdict moved in-scene under it

Default attack -X (left); GOAL label smaller + above the offside wall

three.js: pitch gridlines, goal-direction arrow + label, PNG export

three.js: remove back-projected pitch lines + pitch extension; keep lighter grass/sky

three.js: lighter grass + sky; draw the clicked goal-parallel lines back-projected onto the ground

Add clean three.js offside scene (iframe srcdoc) generated from cached geometry

Auto-lines: default to the goal-parallel family first (was showing perpendicular)

Roboflow-themed UI; threshold default 0.3; ViTDet/RF-DETR detector toggle (boxes/segments); direction arrows

Offside line = furthest-forward marked defender; exclude arms/hands via MHR keypoints

Auto-propose goal-parallel lines (VP-RANSAC) with flip + manual fallback

Back to bounding-box select; up-axis from body vertical (fix leaning players on new clips)

Restore ViTDet-H detector + extract its Mask R-CNN masks (replace RF-DETR for detection)

Part A: RF-DETR-Seg detect (boxes+masks) + reconstruct only selected players at Build

Reorder flow: draw lines on scrubbed frame, split Detect, click-to-select players

Lower detection-confidence slider minimum to 0.0

Robust up-axis: body-up fallback when feet-plane normal is degenerate (fix sideways players)

Redirect HOME/torch.hub/caches to writable /app (fix torch.hub PermissionError)

Add build-essential + ninja for detectron2 compile

VAR offside visualizer
