/**
 * Sintesi Frontend Components — the shared PUBLIC UI kit for the Sintesi Platform.
 *
 * The frontend analogue of shared/sintesi-admin-components.css. Provides the
 * token-driven primitives AND the concept layout patterns (hero, product/content
 * card, category nav, filter rail, sticky summary, value-prop chips, quantity
 * stepper, footer band, tier badges, hand annotation) that every plugin's public
 * page composes from — so visitor-facing UI is one consistent Atlantic system
 * instead of per-plugin forks.
 *
 * Canonical vocabulary: `.sintesi-*` with `--modifier` variants, IDENTICAL to the
 * admin kit — a `.sintesi-btn--primary` renders the same on admin and frontend.
 * Everything resolves through semantic tokens (--bg-*, --text-*, --interactive-*,
 * --status-*, --space-*, --radius-*, --font-*, --shadow-*) which flip to Boreal
 * automatically in dark mode, so there is no separate dark-mode block to drift.
 *
 * Loaded via the shared `sintesi-components` handle (depends on
 * sintesi-design-tokens). Layer the `sintesi-interactions` handle on top for
 * hover/tilt micro-interactions.
 *
 * @package Sintesi\Shared
 * @version 1.1.0
