// Pixel font faces: Jersey 10 for headings and UI labels, Jersey 20 for body
// text, and Jersey 25 (a heavier cut of the same design) as the body bold.
//
// The app refers to two families, "Farmhand Display" (headings, buttons and
// other UI labels) and "Farmhand Body" (running text), so the typefaces
// behind them can be swapped here without touching any components.
//
// These are declared here rather than by importing the @fontsource CSS so
// that each face can set `size-adjust`. Pixel fonts have much smaller glyphs
// per em than the fonts they replaced (Francois One and Public Sans), so
// without it every heading and paragraph in the app would need its
// font-size tweaked. The adjustments below match each face's cap height to
// that of the font it replaced.
