Maintain SCAD-aligned mechanical reference SVGs for this aquarium TEC project. Use for preview SVG fixes, section-view water-path corrections, hose-plug ownership, combined overview cleanup, palette consistency, and XML-safe diagram updates.
Use this skill when working on the cold-block SVG reference sheets rather than the underlying solid geometry.
