/* The shared design system for HVI's standalone customer pages.
 *
 * Wave 0, slice 00C of docs/HVI_VERTICAL_SLICE_MASTER_PLAN.md.
 *
 * WHY THIS EXISTS. Thirteen standalone pages each carried their own copy of the
 * same :root block. The eleven tokens below were byte identical in all five of
 * the pages that define the full set, which is the only reason extracting them
 * is safe and is why it was checked before doing it. The fourteenth page would
 * have copied them again, and then one of the copies would have drifted, and the
 * product would look like it was built by strangers to each other.
 *
 * WHAT THIS IS NOT. It is not a redesign and it is not a new visual doctrine.
 * Every value here was already in the product. No colour, font, radius or size
 * was invented, changed or added. A slice that wants a new token adds it here,
 * once, and says so in its merge request.
 *
 * HOW TO USE IT. Link it before your page's own <style> block:
 *
 *   <link rel="stylesheet" href="/design-system.css">
 *
 * Then delete your :root block and anything below that this file already
 * provides. Keep only what is genuinely specific to your page.
 *
 * BINDING CONSTRAINTS, from standing Founder orders. These are not style
 * preferences:
 *   - No new colour, font, logo, price, offer or visual doctrine may be invented.
 *   - Customer facing prose may never contain a hyphen or any dash character.
 *     Rewrite the sentence instead. This applies to visible copy, not to code,
 *     CSS or attribute values.
 *   - Heirloom Vine Backbone appears only inside approved logo artwork. It is
 *     never loaded through @font-face.
 *   - Never render a provider failure, a raw diagnostic, an internal module or
 *     table name, or a secret where a customer can see it.
