/*
 * ClinicForYou — marketing site.
 *
 * One stylesheet, no build step, no fonts fetched from anywhere: the audience is
 * a doctor or receptionist on a low-end Android phone on a patchy connection in
 * coastal Karnataka, and a webfont that fails to load is a page that reflows
 * under their thumb. System fonts render instantly and support Kannada script
 * natively, which matters for the Kannada version this is structured to take.
 *
 * Palette is the product's own — warm neutral ground, one green accent — so the
 * site and the dashboard read as the same thing.
