/* Clause5 Canonical Signup Form — Shared Component CSS (v1.0)
 *
 * Variant modifier classes preserve per-surface visual identity:
 *   .c5-signup-form--hero    — homepage hero (matches legacy .waitlist-form)
 *   .c5-signup-form--inline  — inline calculator email-gate
 *   .c5-signup-form--card    — Flux widget engagement card
 *
 * Adds nothing to body weight unless a [data-signup-form] mount exists.
 * Honeypot is positioned out-of-flow via inline style on the input (component
 * JS), so this CSS file doesn't need to repeat it.
