   weight axis is pinned there, which halves the file. Optical sizing still
   varies. The 200–800 range below is deliberate: it tells the browser this
   face covers any italic weight, so italic text added later renders at 380
   rather than being synthetically bolded. If you ever want italic at a
   genuinely different weight, restore the full font from git history. */
