/* workflow.murygin.app - the welcome page.
 *
 * Design read: an internal operations entrance for one owner, dark and quiet,
 * built from native CSS with no build step. Two screens only, so the whole
 * stylesheet is one file: a centred password form and a tile grid.
 *
 * Locks: one theme (dark, committed deliberately - this page is only ever
 * opened next to a terminal), one accent, one radius scale, one neutral ramp.
