Overview

Sequences SVG layer output in EA's canonical order:

1. Background <g>
2. (optional) Diagram frame: border + tab + label
3. Per-element groups (shape, header, divider, attrs)
4. Connector + marker groups (merged by style)
5. Labels <g>

Reads diagram.theme once and passes to all child renderers so theme settings (font, colors, stroke width) apply uniformly across the entire SVG output.

Document delegates the layer assembly here so the Document class shrinks to SVG envelope construction.
