/* EAI City — building screen (bld-), chat (chat-), partner ads (ad-), energy (en-). Uses the tokens of css/eai.css.
   The building colour arrives calm (desaturated) as --bc with --bc-ink (icons/text), --bc-l, --bc-ll (tints), --bc-m (borders),
   --bc-d, --bc-dd (dark, for the hero skeleton).
   Hierarchy: a short hero → tabs → the helper's greeting → 4 action cards (+ «Ещё») → 3 examples → the chat → one input. */
