/**
 * Field Notes — newsletter signup component.
 * Used in two variants:
 *   .ppa-field-notes--inline  → drop-in section between page sections
 *                              (homepage, /the-post/, anywhere a shortcode lands)
 *   .ppa-field-notes--strip   → footer fallback (compact)

 * Shares design language with the /the-post/ Send Signal composer:
 * corner brackets, teal scan-line on focus, parchment-on-obsidian, brand fonts.
