home-row-mod-prior-idle.kbd

;; Home row mods with tap-hold-require-prior-idle.
;;
;; This replaces the layer-switching workaround in home-row-mod-advanced.kbd
;; with two native features:
;;
;;   tap-hold-require-prior-idle  — during fast typing, tap-hold keys resolve as tap
;;                         immediately (no waiting state, no accidental holds)
;;
;;   tap-hold-opposite-hand — hold activates only when the next key is on
;;                            the opposite hand; same-hand rolls always tap
;;
;; The result: no nomods layer, no fakekeys, no multi wrappers.
;;
;; Configuration guide:
;;   https://github.com/jtroo/kanata/blob/main/docs/config.adoc#tap-hold-require-prior-idle
