/* ---- Pier gate: the standard Planetek nav, shared by every boardwalk
   property. Self-contained on purpose: fixed pine palette, own fonts, and
   a pknav- prefix so it cannot collide with this plank's styles. The
   hamburger below 960px is a hidden checkbox (the label draws the burger,
   :checked drops the menu) because several planks ship script-src 'none'. */
