Overview

Single source of truth for fill + stroke color decisions.

- Per-type fill colors (elements use default #FFFFFF)
- Text color (#000000 black for non-attribute text)

Precedence chain for fill:

1. Element's BCol int (when present and not sentinel)
2. Default fill (#FFFFFF)

Precedence chain for stroke:

1. Element's LCol int (when present and not sentinel)
2. Theme border color (when theme is themed)
3. Default stroke (#000000)
