/*
 * House style: one look for the Mainfield family of sites.
 *
 * Ampleton's site is the reference. The structure is shared: the type (Poppins for
 * headings, the system sans for reading), pills, cards, bands, the header and the
 * dark footer. A brand sets its own colours, by putting data-brand on <html>:
 *
 *   mainfield   white and black with a little maroon; the company record, and the default
 *   ampleton    terracotta, as on ampleton.ca
 *   lab         burgundy with a field-green band, for lab.mainfield.ca
 *
 * Flat colour only. No gradients, no shadows heavier than a hairline border.
 * No external requests: the font files sit beside this file in fonts/.
