/* BINBOT sign-up dock: the shared skeleton, built once (dock A, "Send bar", David's pick, 1 Nov 2026).
   Every option changes only two things, both set in its own file: the LEFT MARK (.mk) and the JOIN WAITLIST KEY (.k).
   The pill, the field, the placeholder, the labels, the states and BUY $BIN are identical in every option.
   State hooks (set by dock.js, real or forced from the toggles under the dock):
     .dock.is-focus   the field has focus          .dock.has-text  an email is typed (key reads I'M BULLISH)
     .k.is-hover      pointer over the key (hover devices only)   .k.is-press  the key is pressed
     --lv (0..1)      how far the email has got: 0 empty, .25 focused, up to 1 for a valid address. Marks and keys may read it.
   Reduced motion: html.rm (the toggle) or the OS setting; every state still reads without movement. */
