/* ==========================================================================
 * css/core/components.css
 * SPX Moves — Shared component patterns
 *
 * WHAT THIS IS
 *   Ready-to-use, token-driven building blocks for every unified page:
 *   cards, buttons, chips, inputs, tables (grid-based), and modals.
 *   All values come from tokens.css — nothing hardcoded here.
 *
 * HOW TO USE (short version)
 *   Card:    <div class="spx-card">…</div>
 *            <div class="spx-card">
 *              <div class="spx-card-header">Header</div>
 *              <div class="spx-card-body">…</div>
 *            </div>
 *   Button:  <a class="spx-btn spx-btn-primary" href="…">Do the thing</a>
 *            <button class="spx-btn spx-btn-secondary">…</button>
 *            <button class="spx-btn spx-btn-ghost">…</button>
 *   Chip:    <span class="spx-chip">Neutral</span>
 *            <span class="spx-chip spx-chip-warning">In play</span>
 *   Table:   <div class="spx-grid-table" style="--cols:5">…</div>
 *            (use CSS grid, NOT <table>, per wordpress-styling-conflicts.md)
 *   Input:   <input class="spx-input" />   <select class="spx-select">…</select>
 *   Modal:   <div class="spx-modal-backdrop"><div class="spx-modal">…</div></div>
 *
 * SISTER FILES
 *   tokens.css  — the vars this file consumes (must load first)
 *   base.css    — .spx-page / typography (must load before this)
 *
 * LOAD ORDER
 *   tokens.css → base.css → COMPONENTS.CSS → [page-specific CSS]
 *
 * STATUS
 *   Phase 1 — created, NOT yet wp_enqueue_style()'d. See docs/style-unification.md
