/* heads.css — per-agent TOPBAR color slots. structure only, no color.
   the layout, tokenized: each agent's head reads a named slot; the active
   skin fills the slot (skin owns color). slot unset → falls back to chrome,
   so the OZ default is byte-for-byte what it was before this file existed.

   how it works:
     desk.css   .ab-head  { background: var(--head, var(--surface-2)) }
     desk.css   .ab-name  { color:      var(--head-ink, var(--text))   }
     here       map [data-agent] → its slot (--head-<who> / -ink)
     skin       [data-skin="unicorn"] { --head-coder: <pastel>; ... }

   agents with a PNG head (wellness · lumberjack · pa) or their own paper
   token (nurse = --inj-white) override .ab-head themselves — they ignore
   --head and are re-tinted in their own token instead. this file is for the
   DEFAULT-head agents: toto · coder · writer · tutor. */

.agent-bar[data-agent="toto"]   { --head: var(--head-toto,   var(--surface-2)); --head-ink: var(--head-toto-ink,   var(--text)); }
