/**
 * B09 - Newsletter Signup Styles
 *
 * Implements the Saly Front design (B09-NewsletterSignup.dc.html).
 * - Isolated `.saly-ps-` classes (renders on storefront AND in PS /preview).
 * - Neutral / semantic colours use literal Saly Front token values; the brand
 *   ACCENT (button, focus, surface tint, checkbox) is driven by runtime brand
 *   CSS vars `var(--brand-*, <DEFAULT theme fallback>)` so a tenant colour swap
 *   re-themes the block without a rebuild.
 * - Mirrors `.btn`/`.btn-primary`/`.form-control` geometry from the front DS:
 *   40px controls, radius 4px, weight 600, focus ring 3px @ 12%.
 *
 * **NEVER CACHED**: this block contains dynamic CSRF tokens.
