/* ============================================================================
 * DrNick widget · CHARACTER PRESENCE LAYER
 * ----------------------------------------------------------------------------
 * Makes the DrNick character feel present in the UI using ONLY the existing
 * assets (avt-bot.png portrait, bot.png full body) + CSS. No new artwork.
 *
 * Built on the same tokens as widget.css / themes.css, so every state themes
 * automatically (dark default + [data-theme="light"]). Motion is restrained:
 * slow (2.4–3.2s), breathing not blinking, all gated on prefers-reduced-motion.
 *
 * Load order:  colors_and_type.css → components.css → widget.css → themes.css
 *              → avatar.css
 *
 * Reusable presence component:
 *   <span class="dn-ava sm is-thinking"><span class="dn-ava-orbit"></span>
 *     <img class="dn-ava-img" src="assets/avt-bot.png" alt=""></span>
 * Sizes:  xs(28) · sm(40) · md(56) · lg(88) · xl(112)
 * States: (idle) · is-present · is-thinking · is-streaming · is-serious · is-offline
