/*
 * NeccoSpeak — widget styles
 * Everything is scoped with the .neccospeak- prefix to minimize theme interference.
 * widget.js sets brand_color inline as --neccospeak-brand on
 * #neccospeak-root (widget.js:108).
 * A fallback is provided for when it is not set.
 *
 * Class names must match the DOM generated by widget.js exactly (a contract):
 *   Launcher    : .neccospeak-launcher / .neccospeak-launcher-icon
 *   Panel toggle: .neccospeak-panel.neccospeak-open
 *   Header      : .neccospeak-header / .neccospeak-header-title / .neccospeak-close
 *   List        : .neccospeak-messages
 *   Message     : .neccospeak-msg(.neccospeak-msg-user|.neccospeak-msg-assistant)
 *                 > .neccospeak-bubble
 *   Sending     : .neccospeak-typing / .neccospeak-dot
 *   Status      : .neccospeak-status(.neccospeak-status-error)
 *   Input row   : .neccospeak-input-row / .neccospeak-input / .neccospeak-send
 *   Voice       : .neccospeak-voice-btn(.neccospeak-voice-active|.neccospeak-voice-connecting)
