/**
 * XEGHEP FIXED SEARCH PANEL — PROMPT 02
 * 
 * Replaces all floating dropdown behavior with a fixed-position
 * Search Panel that never moves, never resizes, never recalculates.
 * 
 * Panel is NOT an overlay. It is part of the application UI.
 * Only the result list scrolls. Input is always fixed at top.
 * 
 * @package   XOS\Presentation\Search
 * @version   v1.0.0 — PROMPT 02
