/* Phones: the primary routes as three equal tabs in the top strip, the
   current one on the desktop sidebar's amber tile. The strip stays on top:
   at scroll 0 nothing sits under it, where a fixed bottom bar covers
   whatever lands at the fold. This is the one mobile nav rule set: each
   screen's <style> stays injected after leaving it, so a per-screen copy
   would override this sheet by visit order. */
