/* Jolu Chat Redesign — handoff de claude.ai/design 2026-04-18.
 * Escopo: classes `.app`, `.rail`, `.inbox`, `.thread`, `.sidecar`,
 * `.conv*`, `.bubble`, `.msg-row`, `.composer*`, `.copilot*`, etc.
 * Essas classes NÃO existem em outras telas — aplicação só se manifesta
 * dentro do componente JoluChatDesktopRedesign (que as emite).
 *
 * Globals (html/body/#root) do design original foram removidos pra não
 * quebrar outras páginas. Layout usa .app como flex container próprio.
