/* /how: a seven-step guided walkthrough of one question through ChatFPV.
   Same OpenDrone identity tokens as the chat app (gold accent, paper/ink
   neutrals); follows prefers-color-scheme. Layout: one full-screen stage per
   step. The 3D map fills the screen; each step's visual (a board, a passage,
   the answer) floats over it, with a small caption card for the one-line
   explanation, optional "How this works" reading, and Back/Next. */
