Repair report
Doctor Scan results are ready to export as a JSON report.
Character / Sprite mode can now repair one objective high-confidence issue: artwork dangerously close to the canvas edge. It adds transparent safety space while preserving every original artwork pixel exactly. Large padding and asymmetric placement stay review-only because trimming or recentering can change an intended game pivot. Sprite Sheet mode runs Frame Doctor on every occupied cell first, then adds row and sheet diagnostics and the proven sheet repairs.
