/**
 * MxChat AI Search — front-end AI Overview.
 *
 * OVERLAY MODE (default .mxchat-search-overview) is deliberately UNSTYLED:
 * it renders as plain text that inherits the theme's font, size, and colors,
 * so it blends into any site's search results page (Maxwell direction,
 * 2026-07-15: "less is more — just the clean text"). No card, no background,
 * no shadow, no pills. Neutral hairlines only, drawn with a transparent
 * gray that works on light AND dark themes without prefers-color-scheme
 * guessing (an OS-level dark preference must NOT dark-card a light site).
 *
 * REPLACE MODE (.mxchat-search-overview--replace, inside .mxchat-search-page)
 * keeps the styled card treatment — there we own the whole layout.
