/* The entry wall (signup_wall = entry, 2026-10-03): the account ask a
   signed-out visitor meets on arrival. It is #onboard-b3, the same panel as
   every other account ask, lifted over every other overlay (they are all 10,
   style.css) and over the menu's own furniture, because nothing behind it is
   reachable until there is an account. Clerk's sign-in modal portals above
   it; the second-tab curtain (onetab.css, 100000) still outranks it. */
