/* ==========================================================================
   AntJanus — Variable Font Expression
   Two variable families, one axis system:
   - Roboto Flex: display. Width (font-stretch → wdth), weight, grade (GRAD).
   - Recursive: text, UI, code. Casual (CASL), Mono (MONO), slant, cursive.
   Weight and width ride the inherited high-level properties; the custom axes
   ride custom properties so a child never wipes a parent's axis values.
