/**
 * Active frontend font contract.
 *
 * Q01: Latin proportional typography starts with Merriweather Variable.
 * Simplified Chinese then falls through by role to Source Han Sans CN
 * Variable for sans/UI text and Source Han Serif CN Variable for
 * literary/reading text. Code also starts with Merriweather, with Source Han
 * Sans CN Variable covering Chinese glyphs that Merriweather does not contain.
 *
 * The bundled Merriweather files are the upstream variable Roman and Italic
 * builds. They expose real wght 300-900, wdth 87-112 and opsz 7-144 axes, so
 * intermediate weights do not need browser-synthesized Merriweather faces.
 * The Source Han CN variable fonts expose a real wght 250-900 axis, so CJK
 * intermediate weights such as 450 are also rendered from real interpolation.
