/* =============================================================================
   Reference chips — a name with a fact, on the ground, that she can take off.

   ⭐ PROMOTED OUT OF EXPLORE (2026-09-09). Explore has drawn exactly this since
   before Design 2.0: a wrapping row above the input, one chip per reference
   she typed with `@`, each carrying a mark that says person-or-entry and a
   `×` that removes it. The composer's *Related to* row is the same object —
   a reference Pensio holds beside her words, never inside them — so the
   rules moved here rather than being spelled a second time.
   📐 docs/ideas/a-reference-that-is-not-in-her-words.md

   ⚠️ TWO THINGS THE PORT CHANGED, ON PURPOSE. The old block hard-coded
   `rgba(92, 107, 89, 0.08)` and `border-radius: 20px` where tokens now exist,
   and it painted a person chip and an entry chip in two tints six hundredths
   apart — a difference nobody could see. The chip's MARK says which kind it
   is (Explore draws a person / a pen; the composer uses `{% icon %}`), so
   there is one chip recipe and the two kind classes stay as hooks.

   ⛔ NOT A `.card-surface`, NOT A `.badge`. A badge is a state or a kind
   (Draft, Beta) and is never interactive; a chip names one thing she chose
   and carries the control that un-chooses it. Never uppercase, never 700.
