/* PICPACS SITE CHAT WIDGET
   Self-hosted, backed by src/chat.js + a private Telegram bot (see
   13-Site-Chat-Widget.md). Matches the "stoic." design tokens from
   style.css (black/white/gray, pill buttons, soft-shadow circle badges);
   falls back to the same literal values so this file also works standalone
   if style.css isn't on the page. Scoped entirely under #picpac-chat so it
   never leaks into the rest of the site. To disable the widget, remove the
   <link>/<script> tags that load this file - nothing else changes. */

/* .pp-panel/.pp-badge/.pp-contact each set an explicit `display` below to
   lay themselves out when shown; toggling the `hidden` attribute doesn't
   ask the browser to fight its own default [hidden]{display:none} rule
   unless we say so explicitly - author CSS beats the UA stylesheet at
   equal specificity, so without this line these three would stay visible
   even with .hidden = true. Keep this ahead of any specificity questions. */
