Token-Based Theming

Instead of ggplot2's 90+ theme() arguments, glyph uses a design-token system. A small set of semantic tokens (font, colors, spacing, sizes) cascade through the entire visualization. Think of it like CSS custom properties for plots.

Tokens cascade: setting bg changes the background, but also automatically adjusts text color for contrast, grid line opacity, and tooltip styling. You override only what you want; everything else adapts.
