   Consumes tokens.css only (design-spec.md §10). Covers: layout container,

   (matching the .dc.html reference approach) or in a small <style> block at

   pre-resolve fallback, not a permanent dormant flag.

   min-width reserves this slot's full logged-in footprint (Hi, {name} + Log
   Out + Demo + Sample Demo — measured ~474px for a short name) from the
   very first paint, while [hidden] keeps it invisible via visibility rather
   than display:none. Without this, the slot went from zero width straight
   to ~470px+ the instant auth resolved, shoving "Analyze My Space" (and
   everything after this slot) sideways by that much with no warning — a
   visitor who moved to click something during that reflow could land on
   Log Out instead. Reserving the space up front means resolving auth only
   ever swaps content inside a box that was already there; nothing to its
   right moves. */
