/* Simple-PSA paid signup — styles. STA-8618.
 *
 * signup.html is a standalone page, so unlike site/try-now.css (which inherits
 * the custom properties index.html already defines) this has to restate them.
 * The values are copied from the live simple-psa.com :root block so the two
 * pages are the same product; keep them in step if the landing page's palette
 * changes. tests/test_billing.py asserts the primary and canvas values still
 * match the ones recorded here, so a drift shows up as a failing test rather
 * than as a signup page that looks like a different company's.
