 * the same tokens/buttons/modals/tables. Page-specific layout (the
 * unique panels/grids each page needs) stays in that page's own

/*
 * IBM Plex, served from this machine.
 *
 * These used to come from fonts.googleapis.com, linked in the <head> of
 * 31 templates ABOVE this file. That is a render-blocking request to the
 * internet in an app that otherwise never leaves the LAN, and the lab's
 * Wi-Fi has no reliable internet: iPad Safari would block first paint
 * until the request timed out, every cold page load. It never showed on
 * the server PC, which had it cached.
 *
 * It bit the iPad harder than a Windows client for a second reason - the
 * fallback stack below is 'Segoe UI', which does not exist on iPadOS, so
 * the iPad had more reason to sit and wait for the webfont.
 *
 * latin subset only: its range is U+0000-00FF, which covers the N-tilde
 * in Filipino patient and clinic names. latin-ext would only add Eastern
 * European characters this lab has no use for.
 *
 * IBM Plex is SIL Open Font License 1.1, so redistributing it inside the
 * .exe is fine. Sans is a variable font - all four weights are the same
 * file, declared separately exactly as Google's own stylesheet did.
