v0.3.1 — Proper Horizontal Tank, Zoomable Viewer, Embedded Graduations

Fixes

Horizontal Cylinder

• Fixed: Was rendering as a broken bowtie/hourglass shape
• Now: Proper ellipse/capsule shape (like a real propane tank on its side)

Tank Viewer

• Expanded to 50% of screen width (was cramped 220px column)
• Zoom controls: +/- buttons, FIT reset button, mouse wheel zoom (0.5x to 3x)
• All vessel types now render in a 400x300 SVG viewBox (sharper at all zoom levels)

Graduations

• Height and percentage graduation marks are now embedded directly on the SVG
• Left side: height values (cyan) with major/minor tick marks
• Right side: percentage scale (purple)
• Yellow dashed level indicator line with percentage label
• Marks stay accurate when zooming — no more misaligned external rulers

Visual

• 3-stop liquid gradient for more realistic depth appearance
• Removed external HTML ruler elements (replaced by SVG-embedded marks)
