;;   tui.bb [--headless] [--demo] [--cols=N] [--rows=N] [--wait=MS] [--dump]
;;
;; run.bb with the other backend under it, and the same two halves: the frq
;; source is the files on disk, and everything below it is the flake's. The
;; dev shell builds jolt-native and names both Jolt sides of it — glimmer-vidya
;; for the window, glimmer-tui for the terminal — so this needs no checkout
;; beside the tree and no library fetched by digest.
;;
;; It still loads libvidya as well as libjolttui. `frq.app` requires
;; glimmer-vidya, and `frq.tui` requires glimmer-tui after it so the backend
;; installed last is the terminal; the window's library is resolved and then
;; asked for nothing.
;;
;; No nixGL here, unlike run.bb: a terminal wants nothing from the host's GL
;; driver, which is the reason this output exists on machines that have none.
