/**
 * Which inline spec hosts the "Search Peach…" chip.
 *
 * v2.14.6 collision fix (holds): with a single inline spec and an OTP chip
 * eligible, both chips would target specs[0] and the picker dataset -- added
 * last -- would clobber the 2FA chip. The picker drops to the system menu so
 * the OTP chip keeps the lone slot.
 *
 * v2.14.8 refinement: without an OTP chip the stale two-slot reservation
 * left the last spec empty (and with 2 specs the entry budget at zero). The
 * picker now anchors the last slot itself when no 2FA chip is eligible.
