 * Portal typeface: the native system UI font stack (client, 17-Oct-2026 — replaces Times New Roman, 01-Oct-2026).
 * Every reader sees their own operating system's interface font, so nothing is downloaded. The family is set
 * once, as --vz-font-sans-serif in custom-theme.css (the variable name is the template's). Imported by
 * custom-theme.css (every shell) and linked directly by the standalone pages (index, account, the print pages).
 * Generated documents (server PDFs, the table PDF export, docx, xlsx) keep Times: they cannot use a system stack.
