Shell (main-chat-shell-spec): rail rebuilt around a 48px squircle claw
avatar stack with a 2px coral active ring + name beneath + online dot,
dashed 'New claw' tile, lucide-icon nav pills with the live credits
balance shown inline (coral when negative, aria-hidden so the nav link
name stays 'Credits'); 80px transparent chat header with 36px round
sessions/new-session icon buttons and the 42px coral-glow Computer
launcher; 768px centered content rail. RosterList computes the active
claw from the pathname so AgentRosterItem stays presentational.
Chat (chat-message-components): asymmetric layout — user pill #1A1A1A
radius 24/24/4 with inset white ring + dual shadow, capped 75%, vs the
bubble-less assistant message (50px squircle avatar, 15px gap, plain
14px/1.7 text); messageSlideIn entrance; 126px welcome avatar with the
24px/600/-0.6px heading (claw name in coral) and lucide-led suggestion
chips; floating 24px-radius neutral-800 composer card with the cream
Send pill; StepTrace rows restyled to the system.
Brand marks (Chrome, Slack) vendored to public/services from the bundle.
83 unit tests, full 29-journey functional E2E green.
