/* ============================================================================
   ocellio — /graph (Graph v3, Spec §5.6, a47): full-height grid of canvas +
   control bar | sidebar, the SVG classes of hulls, nodes, edges and relation
   pills, the filter overlay, the Stand pill and the sidebar ("Was sich bewegt
   hat" / node panel). Loads after auth.css. Project colours via pjb-N →
   --pj-cur (components.css), kind colours as SVG attributes from
   kind_palette; states are classes here, never inline (CSP).
   Text contrast ≥ 4.5:1 in both themes: small labels use --faint (not
   --faint2) or --muted, project colours as text are mixed towards --fg,
   accent text uses --g-accent-text (--accent-hi on navy). Kind and project
   colours under or behind an initial are darkened in oklab (review a47,
   pinned by tests/web/test_graph_contrast.py): node initials 70 % on the
   light node fill of both themes, the white initial of the panel badge on
   75 %, of the project node on 82 % (as the a41 cross badge).
