/* --- A22.3: formulation timeline (positioning-safe) -----------------
   D013 review notes: NEITHER chip uses a green/red palette. Both share
   the neutral base .chip foreground; the ＋/− glyph carries direction.
   chip-remove gets strikethrough as a color-independent affordance.

   Post-review fixes:
   * override inherited `cursor: pointer` and `min-height: 32px` from the
     base .chip class — the formulation chips are non-interactive; a hand
     cursor implies false affordance and the forced 32px height wastes
     vertical space in the compact timeline row layout.
   * add ≤480px stacking so long INCI tokens don't crowd the middle
     column on mobile (iPhone 393px inner-width ≈ 369px).
