work nav: thin top bar + click-through fix

- #worknav offcanvas collapses to a 68px bar (bottom:auto releases the
  base .offcanvas bottom:0 so height:auto no longer stretches full-height)
- z-index 990 keeps the side-nav 'Who' link painted above where they overlap
- pointer-events:none on the full-width .header-small bar (auto on its
  links/hamburger) so both navs stay clickable
