 * families, and then leans on `body { font-family: var(--md-text-font-family) }`
 * - but the *-family variables are derived inside Material's own stylesheet,
 * which this engine does not load. Without these two lines that var() is
 * undefined, the declaration is invalid, and every page falls back to the
 * browser's default serif. Deriving them the same way Material does keeps the
 * shared file working unchanged, font toggle included.
