/* Doqmah · the project-request form (/request and /en/request).
 *
 * Loaded after style.css (tokens, font, reset, .btn) and legal.css (the .doc page frame).
 * Logical properties throughout, so the Arabic (rtl) and English (ltr) pages share one file.
 * No inline <style> or style="" on these pages: the CSP allows exactly one inline style hash,
 * and it belongs to 404.html.
 *
 * Without JavaScript the Worker answers a submit with a 303 to #sent or #error, and :target
 * below shows the matching panel. With JavaScript, request.js toggles .is-shown instead.
