Module segment 

Segment system for styled text units.

A Segment is the atomic unit of styled text that can be:

• Cheaply borrowed (Cow<str>) for string literals / static content
• Split at cell positions (not byte positions) for correct wrapping

Segments bridge higher-level text/layout systems to the render pipeline.

Example

use ftui_text::Segment;
use ftui_style::Style;

// Static text (zero-copy)
let seg = Segment::text("Hello, world!");
assert_eq!(seg.cell_length(), 13);

// Styled text
let styled = Segment::styled("Error!", Style::new().bold());

// Split at cell position
let (left, right) = seg.split_at_cell(5);
assert_eq!(left.as_str(), "Hello");
assert_eq!(right.as_str(), ", world!");
