/**
 * Self-contained default styling for the chat widget, written entirely
 * against CSS custom properties (see class-ca-ai-chat-public.php) so
 * re-theming per site is a settings change, never a CSS edit. Every
 * property has a literal fallback too, so the widget still looks
 * reasonable even before the inline :root override loads.
 *
 * Uses the .ca-chat/.ca-msg/.ca-chat-row/.ca-chat-send class names the
 * cawt-2026 theme's own hero demo already established, so on that site
 * this widget drops into the existing .panel-ai container without any
 * theme-side CSS changes — but every rule here is self-sufficient, since
 * this plugin also needs to work standalone on any other WordPress site.

/* Root cause, found while chasing this same readability problem across
   several rounds: cawt-2026's parent theme ("Improvise") has a global
   `p, li, pre { color; font-family; font-size; line-height; }` rule
   (improvise/style.css) that targets those bare elements directly. CSS
   only falls back to inheriting a property from an ancestor when nothing
   targets the element itself — so that rule always wins over whatever
   .ca-msg-them's own color/font-size resolves to, regardless of
   selector specificity or !important on the ancestor rule, for any
   property it sets. Assistant replies are real markup (see
   renderMarkdown() in chat-widget.js) — p/ul/ol/li/strong tags — so they
   get caught by it; the visitor's own message (.ca-msg-me below) is
   plain text with no such tags, so it was never affected. This one rule
   explains every readability report so far (color, and now font-size)
   — fixed once, here, for every property that rule sets, rather than
   chasing them one at a time. Margins are trimmed from browser defaults
   to read as one continuous chat bubble, not a spaced-out document, and
   the first/last child's margin is zeroed so the bubble's own padding is
   the only space above/below the text. */
