   - Variable axes: wght 100–1000, opsz 6–144, ROND 0–100, GRAD −200–150, slnt −10–0
   - Static optical-size cuts also self-hosted under fonts/, exposed as:
     ‘GS Flex Caption’ (9pt)  ·  ‘GS Flex Text’ (24pt)  ·  ‘GS Flex Body’ (36pt)
     ‘GS Flex Display’ (72pt)  ·  ‘GS Flex Hero’ (120pt)
   The variable face is primary and handles opsz automatically via
   font-optical-sizing: auto on body. Use the static aliases only when
   you need to lock the optical cut explicitly (e.g. print). */
