		Previously I was going to use https://pkg.go.dev/github.com/chelnak/ysmrr for this.
		Namely because I *thought* it was the only spinner lib that can do multiple spinners at once.
		(Even submitted a PR, https://github.com/chelnak/ysmrr/pull/88)

		HOWEVER, all spinners are synced to use the same animation... which means they all use the same
		frequency/rate of update.
		I want to sync it so the "animation" ends when the TOTP runs out (or thereabouts).

		pterm to the rescue.
