/**
 * SG Assistant — Front-end widget styles.
 *
 * This stylesheet defines every visual aspect of the chat widget. It
 * is designed to be completely isolated from the surrounding theme
 * (every selector is scoped under `.sg-root`) and to inherit the
 * theme's typography and colors whenever possible, so the widget
 * looks like a natural part of the site rather than a foreign
 * element.
 *
 * =====================================================================
 * STRUCTURE
 * =====================================================================
 *
 * The file is organized into twelve sections:
 *
 *   1.  TOKENS       — CSS custom properties (design system).
 *   2.  RESET        — box-model and inheritance normalization.
 *   3.  ROOT         — the widget's outer container.
 *   4.  LAUNCHER     — the floating button and the teaser.
 *   5.  PANEL        — the widget's main surface.
 *   6.  HEAD         — the panel's header.
 *   7.  FEED         — the message log.
 *   8.  CARDS        — the result cards and their breadcrumbs.
 *   9.  CHIPS        — the suggestion chips.
 *  10.  COMPOSE      — the input form and the send button.
 *  11.  TYPEAHEAD    — the live-search dropdown.
 *  12.  RESPONSIVE   — mobile adjustments and reduced-motion support.
 *
 * =====================================================================
 * DESIGN TOKENS
 * =====================================================================
 *
 * Every color, spacing value, and radius is defined as a CSS custom
 * property on `.sg-root`. This makes the widget trivially themable:
 * a theme can override any token by setting it on `.sg-root` (or on
 * `:root`) after this stylesheet loads. The harmonization script
 * (`chat.js`) writes some of these tokens at runtime based on the
 * site's own colors.
 *
 * The tokens fall into five groups:
 *
 *   - `--sg-accent*` — the primary brand color.
 *   - `--sg-bg`, `--sg-surface`, `--sg-line` — surfaces and borders.
 *   - `--sg-text`, `--sg-muted`, `--sg-on-accent` — text colors.
 *   - `--sg-radius*`, `--sg-shadow` — shape and depth.
 *   - `--sg-size`, `--sg-*-icon-size` — sizing.
 *
 * =====================================================================
 * ISOLATION STRATEGY
 * =====================================================================
 *
 * Every selector in this file begins with `.sg-root` (or, for the
 * dark-mode overrides, `.sg-root.sg-dark`). This guarantees that the
 * widget's styles cannot accidentally leak into the surrounding page,
 * even when the theme uses aggressive global selectors like
 * `button { ... }` or `* { box-sizing: content-box }`.
 *
 * In addition, the widget resets every inherited property that a
 * theme might have set in an unexpected way (`letter-spacing`,
 * `text-transform`, `text-shadow`, `box-shadow`, `background-image`,
 * and so on) at the root, so the widget starts from a known state.
