  /* ---- Editorial serif scale ----
     Instrument Serif ships ONE weight, which is correct for a display face and
     wrong for mid-hierarchy. So the serif is scoped by SIZE, not by weight:
     at or above --serif-floor the serif leads; below it, IBM Plex Sans takes
     over at a real 600. Never request 500/600/700 from --font-serif — the
     browser will synthesise it and the letterforms distort.
     Every step below clears the floor. ---- */
