/* ──────────────────────────────────────────────────────────────────
   Polish fix — Chat fullscreen overlay + header-integrated button
   Spec: docs/superpowers/specs/2026-05-11-track-c3-bottom-nav-design.md
   Replaces the original slide-up panel with a true fullscreen modal.
   Bubble button lives inside the OV header (not floating) — see
   index.html for the markup.

   .ov-icon-btn inside the header; remove the old fixed-position styles
   that the previous markup relied on. */

    /* No special positioning; styled by .ov-icon-btn in obsidian-vault.css */

/* The unread badge on the chat-bubble. Uses #chat-bubble-badge id with
   .ov-badge class — same visual as notif-badge. No extra rules needed,
   .ov-badge styles cover it. */
