/* Walking mode. Tokens come from /style.css. The dock is ink; the plan and
   the place reading are paper. Movement, collision and camera behaviour are
   untouched: this sheet only positions and styles the existing controls.

   Layering contract for anything anchored to the bottom edge:
     --dock-h       height of the walking dock at the current breakpoint
     --dock-gap     space between the dock and the next overlay
     --narration-h  extra lift applied while #narration-player is visible
   Every bottom-anchored overlay (directions, arrival hint, thumb control,
   look hint, narration player) is offset from these, so they stack instead
   of colliding. See outputs/claude-ui/HANDOFF.md for the narration notes. */
