/**
 * Chamber Membership — public registration form styles.
 *
 * Theme integration (Part 16 of the architecture):
 * The --chamber-* variables below try, in order: a full-site-editing
 * theme's theme.json color palette (--wp--preset--color--*, available
 * on virtually every modern block theme, so this is the primary
 * target), then a couple of common page-builder globals as a
 * secondary attempt, then a neutral hardcoded fallback if neither is
 * present. The plugin never assumes a specific theme or builder.
 *
 * Kept restrained per Part 17 — no gradients, no motion beyond a
 * quick property transition, no decorative imagery. Visual interest
 * comes from spacing, borders, and a very light tint on the card and
 * on the selected membership level, not from ornamentation.
