claude.theme: a dark irssi theme whose colours map 1:1 to the roles
Claude Code uses in its default dark UI:
#8c8c8c dim timestamps, brackets, connective text
#f85149 red errors, netsplits, parts, private msg frames
#56d364 green joins, ctcp, dcc, netjoins, quiet activity
#e3b341 yellow messages-to-me, /me, statusbar chatter
#4a9eff blue channel names, pubnicks, diff-style accents
#c9a3ff magenta own nick / prompt / notices / hilights
#4ec9b0 cyan whois field names, info lines
Uses 24-bit true-colour escapes (%z<rrggbb>) so the shades land
exactly regardless of terminal palette. Requires irssi 1.2+ and a
truecolour-capable terminal (modern xterm/tmux both are).
irssi/config: switch the active theme from rainbow-dark to claude.
