Ncurses Render Safety

Use this skill for rendering, color, redraw, or window-painting changes.

Core Rules

Set window background once per refresh path, not per line.
After setting a new window background, clear with werase() before redraw.
Use wattron()/wattroff() for line-level styling only.
Keep redraw ownership clear: you MUST NOT introduce hidden side effects across modules.

WbkgdSet Rule

WbkgdSet() applies to the full window background state.
Do not call it inside row/entry rendering loops.
Typical safe shape:
- Set background once in top-level display function.
- werase() the window.
- Render lines with temporary attributes.

Verification Checklist

No repeated WbkgdSet() in per-item loops.
No background color bleed between entries.
No flicker introduced under frequent refresh.
Active/inactive panel visuals remain consistent.
