/*
 * Hickory Chair · Designer Collections
 *
 * Shared styles for two surfaces:
 *   • collections.html   — the designer-led index (8 collection cards)
 *   • collection.html    — single-collection detail (hero + bio + pieces)
 *
 * Tokens duplicated locally (rather than relying on a host page :root)
 * because index.html embeds the same markup inside its Collection tab and
 * the brand tokens there live inside the page <style> block, not a global
 * stylesheet — the duplication keeps both surfaces visually identical.
