highlighted_hash lit a key's path-hash prefix in the fixed brand cyan; it now takes the node's hash-derived palette hue — the same colour the node's name wears — so a hash carries its node's identity colour even where no name is known, and a key's prefix, its name, and its map labels all agree. The remainder (and a hash standing in as a name) stays muted, and the truncation ellipsis keeps inheriting the colour of the digit it replaces. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
