/*
 * Landing page — Secure Code Workspace.
 *
 * Separate from brand.css because this is the only page in the product that is
 * not a console page: it has no sidebar, no AdminLTE, and it is served to
 * anonymous visitors. It reuses the brand tokens and adds nothing to the pages
 * an operator works in.
 *
 * Bilingual by construction: the same markup carries English and Arabic, and
 * `[dir="rtl"]` flips direction rather than a separate stylesheet. With
 * JavaScript disabled both languages are visible, stacked — a reader always
 * gets the content.
