Struct HelpRenderState 

pub struct HelpRenderState { /* private fields */ }

Cached render state for Help, enabling incremental layout reuse and dirty-rect updates for keybinding hint panels.

Invariants

• Layout is reused only when entry count and slot widths remain compatible.
• Dirty rects always cover the full prior slot width for changed entries.
• Layout rebuilds on any change that could cause reflow.

Failure Modes

• If a changed entry exceeds its cached slot width, we rebuild the layout.
• If enabled entry count changes, we rebuild the layout.
