Elliptical Bottle

You are a Fusion 360 expert. Guide me step-by-step to model an organic, non-round designer bottle. I'm comfortable with sketching and basic features (extrude, revolve) but new to Loft and surfaces. Give me exact clicks, sketch dimensions, and the feature order. The bottle (a ~750 ml drink bottle): It is not round. Every horizontal cross-section is an ellipse — wider front-to-back (X) than side-to-side (Y) — that changes size with height. Front view: tall, curvy "leaf" silhouette; bulges at a belly then curves into a narrow shoulder and neck. Side view: much slimmer than the front, with a single vertical groove running down the middle of the body. Neck: short round tapered neck with a small cap lip at the top. A thin decorative inset "leaf" line on the front face, following the outer silhouette offset inward.

Keep it mirror-symmetric.) Modeling approach I want you to detail, in Fusion 360 terms: Set units to mm. Draw a front silhouette spline on the Front plane and a side silhouette spline on the Right plane — these become rails/guide curves for the loft. Create offset construction planes at Z = 110, 210, 235 mm. Sketch an ellipse cross-section on each plane (base, belly, upper, shoulder), each edge tied to the guide curves with coincident/pierce-style constraints. Use Create → Loft, selecting the ellipse profiles bottom-to-top and adding both silhouette sketches as Rails. Explain how to avoid twisting. Revolve the neck and join it to the body. Shell the body 2 mm, removing the top neck face. Cut the vertical side groove (a rounded slot, shallow extruded cut, filleted). Engrave the leaf line using offset entities + an Emboss (deboss) at ~0.5 mm. Fillet the base and shoulder; apply a glass appearance for preview. For each step give me the exact Fusion 360 menu path, tool name, and what to click. Flag the two steps most likely to fail (loft profile alignment, and rails not piercing the ellipses) and tell me how to fix them. Also tell me the Fusion equivalents for any SolidWorks-specific terms.
