   JG-COMMUNITY-TREES.CSS  -  Jewish Communities Tree
   Project Shorashim / JG40-Build
   CHW - 27 July 2026
   ----------------------------------------------------------------------------
   Loaded ONLY by /Communities/Trees/. Stylesheet load order on that page:
       1. Bootstrap CDN
       2. /jg-global.css
       3. /Communities/jg-community-trees.css   <-- this file

   NOTE: the tree page does NOT load jg-community.css. It was checked class by
   class - the page uses 22 .ct-* rules from this file plus .page-title-band,
   .tagline, .hero-subtitle and .jump-bar, all of which are global. Nothing in
   jg-community.css (town pages, search form, search results, Leaflet map) is
   referenced, so loading it would be dead weight on every visit.
   ----------------------------------------------------------------------------
   DUPLICATION WARNING, READ THIS FIRST.
   These rules are near-identical to the .inv-* block currently sitting inline
   inside /databases/Cemetery/tree/CemList.php. Two copies of one pattern is
   exactly the drift the style standards warn about.

   RECOMMENDED FIX (not done here, because it means editing jg-global.css and
   touching a working JOWBR page): promote the shared parts - tree, folder,
   chevron, leaf, filter bar, spinner, mark - to jg-global.css as a .jg-tree-*
   component, then have BOTH pages use it and keep only their genuinely local
   bits. The era tabs below are genuinely local to Communities; JOWBR has no
   eras. Everything else is shared.

   Until that happens: if you change one, change the other.
   ----------------------------------------------------------------------------
   TOKEN DISCIPLINE
   Navy is never used as a background via var(--navy) - it flips to light gray
   in dark mode. The one navy fill (the selected era tab) is hardcoded
   #09497a / #0d2a45 per the dark mode hazard.

   Three time periods over the same 6,359 communities. Not the same thing as
   the section sub-nav above them, so they are deliberately styled as segmented
   controls rather than a second tab strip - two identical-looking nav bars
   stacked would be unreadable.
