/* hab-path web preview. Every rule lives here: the production CSP is
   style-src 'self', which silently refuses inline style= attributes — the
   page renders fractionally wrong with nothing but a console error as
   evidence. CSSOM assignment stays exempt, so canvas/JS sizing is fine.

   Two consequences worth stating out loud, because they are easy to undo:

   1. Nothing in this file styles or selects the site bar. build.py splices
      that <aside> in as body's first child and ships its own stylesheet,
      linked AFTER this one, so a rule here would lose the tie anyway. The
      page is pure document flow with a fixed-pixel #map for exactly that
      reason — the bar can push everything down without breaking the map box.

   2. Anything JS injects (a Leaflet divIcon, a popup, a waypoint row) must
      carry a CLASS, never a style= attribute. That is why the marker colours
      below are .hab-marker.launch and friends rather than a colour
      interpolated into the icon's html string. */
