Crate ftui_style 

Style types for FrankenTUI with CSS-like cascading semantics.

Role in FrankenTUI

ftui-style is the shared vocabulary for colors and styling. Widgets, render, and extras use these types to stay visually consistent without dragging in rendering or runtime dependencies.

This crate provides

• Style for unified text styling with CSS-like inheritance.
• StyleSheet for named style registration (CSS-like classes).
• Theme for semantic color slots with light/dark mode support.
• Color types and downgrade utilities.
• Table themes and effects used by widgets and markdown rendering.

How it fits in the system

ftui-render stores style values in cells, ftui-widgets computes styles for UI components, and ftui-extras uses themes for richer rendering (markdown, charts, and demo visuals). This crate keeps that style layer deterministic and reusable.
