Research Dossier (baked into the plans)

The 1937 Tatra 97 is a streamlined teardrop sedan engineered in Kopřivnice (1936–1939). Hallmarks: rear-mounted air-cooled flat-four (1,749cc), 4-speed transaxle, advanced aerodynamic body, and historic design influence.

• Silhouette priorities: long teardrop tail, smooth roofline, rounded fenders, narrow greenhouse, tapered rear deck.
• LEGO translation: tile-smooth shell, SNOT ribs, bracket-locked curvature, and a hidden Technic spine for load paths.
• Museum cues: simple period hubcaps, minimal trim breaks, clean two-tone boundary, and realistic cabin proportions.
• Validation: BrickLink Studio collision + connection check, no floating, no stressed geometry, all pins/axles align straight.
