/**
 * Links Inventory — Chem Chemical Data Suite
 * Frontend Product Information Stylesheet
 *
 * @owner      Links Inventory (linksinventory.com)
 * @copyright  2026 Links Inventory. All rights reserved.
 *
 * PURPOSE
 * ───────
 * Styles the Product Information table on the WooCommerce single product page.
 * Designed to match the Astra theme — white background, clean typography,
 * with the Links Inventory cyan accent (#06b6d4) for the header and labels.
 * All selectors scoped to .ccds-chemical-data — zero bleed into theme styles.
 *
 * DESIGN DECISIONS
 * ────────────────
 * - Cyan left border on label column gives a "chemistry document" feel
 * - Monospace font only for technical values (SMILES, InChI, InChIKey)
 * - Long technical strings truncate on mobile — no horizontal scroll
 * - Missing values shown as a grey dash (—) not the word "NA"
 * - Storage text truncated in PHP to 180 chars before reaching CSS
 * - CAS number styled as a subtle external link to PubChem
