/**
 * VisaBreeze Chat widget.
 *
 * Colour is anchored on the site logo's blue (#2563EB) with a cool neutral
 * scale. Every pair was
 * measured rather than eyeballed: the previous accent failed WCAG AA at 3.72:1
 * both as a link and as white-on-blue, and the bot bubble sat at 1.07:1 against
 * its surface, which is why messages read as flat text. Now: links 6.53:1,
 * white on the user bubble 13.8:1, ink 17:1, and bot bubbles carry a hairline
 * because a light surface on a light surface is defined by its edge, not by
 * pushing fill contrast until it looks like a box.
 *
 * Depth ramps stay within one hue. The old header went navy to purple at
 * near-equal value, which reads as mud; value alone reads as depth.
 *
 * Motion runs on three tokens rather than thirteen loose `ease` declarations,
 * so everything decelerates on the same curve and the widget feels like one
 * object.
 *
 * EVERY rule is scoped under the #vb-chat-root ID on purpose. Astra and
 * Elementor style bare `button` elements site-wide, and single-class selectors
 * lose to them: the chips rendered as dark rectangles and the round launcher
 * came out square. The ID prefix wins that fight, and the `#vb-chat-root button`
 * reset re-states the properties the theme sets rather than trusting inheritance.
 *
 * Thai has no word spaces, so long strings must be allowed to wrap on any
 * character (overflow-wrap) but never word-break, which splits Latin brand
 * names like "VisaBreeze" mid-word. Line height is generous because Thai
 * stacks vowel and tone marks above and below the baseline.
