/* House Synergy flyer archive (/flyers/), built by tools/flyers.py.
   Tokens, header, buttons and footer copy the home page, whose CSS is inline in index.html: keep the two in step.
   The page works without JavaScript (flyers open as plain images); js/flyers.js adds the full-size viewer.
   No animation. The header is not sticky, so it never covers the focused link. */
