/*
 * Oracle chat — visual layer (Fable-owned; behavior lives in oracle-chat.js).
 *
 * PRIMARY: the chat is EMBEDDED at the bottom of the floating control panel
 * (`.panel-chat` inside `.galaxy-panel` in index.html — ids oc-messages /
 * oc-input / oc-send). Styled to read as the panel's footer dock: same glass,
 * ORACLE-orange accent, compact type to fit the 272px panel.
 *
 * FALLBACK: if that markup is ever missing, oracle-chat.js self-mounts a
 * floating bubble (`.oc-fab` / `.oc-panel`). Those styles are kept at the
 * bottom, scoped so they never leak into the embedded look.
 *
 * Message classes applied at runtime (shared by both mounts):
 *   .oc-msg .oc-user .oc-oracle .oc-hint  — bubbles
 *   .oc-note                              — small meta line
 *   .oc-typing                            — three-dot indicator
