Fano-plane palette scheme: the 7 colors map onto 7 CGB BG palettes so
any color pair shares one palette; a tile's palette is picked from the
set of colors its two cells need (tables generated by tools/gencolor.py).
Per cell a packed (bg<<4)|fg byte lives alongside the char shadow, and
the glyph blitter steers glyph/empty pixels to each cell's fg/bg color
slots via plane masks.
An ANSI-ish CSI parser (ESC [ .. m) drives it; usr/ansi.c demos it and
the irc client now renders hashed nick colors, status dimming and a
channel-activity bar.

Userland sources live in usr/ (fits the Unix theme better than 'c').
SDCC output .bin blobs land in build/usr/ with the other build artifacts
instead of littering the source dir; programs.asm INCBINs them from there.
Byte-identical ROM.

'/join #sl0p right after connect' looked broken: the main loop only
polled input when net_recv_nb returned nothing, and 'continue'd on every
received segment. During a big MOTD (irc.sl0p.foo's is ~60 lines of
color art) that starved input for the whole ~20s flood - the OSK
wouldn't even open, and keystrokes were dropped. gbtype input fared a
bit better (buffered in the 64-byte console ring) but still wasn't
serviced until the flood ended.
Poll pollin()/pollcon() once every loop iteration regardless of RX, and
only idle-sleep when a pass both received nothing and read no key. The
protocol/join logic was already correct (verified: JOIN #sl0p is sent,
accepted, and the client switches to [#sl0p] with topic + names) - this
just makes typing responsive while messages are streaming.
Verified against the live server: injecting /join #sl0p *during* the
MOTD flood now joins immediately instead of waiting it out.
(Note: '#' is on the OSK - third row, second from the end:
10,8,":;,=+*_!?()[]<>@#~" - just not obvious.)

Against the real irc.sl0p.foo (via a TLS-stripping socat proxy) the
client's screen filled with garbage after connect. Two causes:
1. Color/format codes. The MOTD is a mIRC-color ASCII-art logo. We
dropped the \x03 control byte (term ignores <32) but left its numeric
*arguments*, so the logo rendered as digit soup ('09> stream the
work', '030903 030903 ...'). strip_fmt() now removes \x03 color (+its
fg[,bg] digits), \x04 hex color, and the \x02/\x0f/\x11/\x16/\x1d/
\x1e/\x1f toggles, applied to the trailing text of every line (leaving
\x01 for CTCP). Standalone digits like '3 apples' are untouched.
2. The real bug: handle() defaulted pfx/txt to a read-only "" literal,
and both bang(pfx) and strip_fmt(txt) write a NUL terminator into it.
That literal lives in ROM (000-FFF); on MBC5 a write there is a
RAM-bank-select, silently swapping the cart-RAM bank - where
every static lives - out from under the program. One prefix-less or
empty-trailing server line (real ircds send them: NOTICE AUTH, ERROR,
registration PING) and all state turns to garbage. Fixed with a
writable 1-byte 'empty' default (zeroed in main; gbos doesn't clear
BSS).
Also suppress 004 (MYINFO) and 005 (ISUPPORT) - pure noise on 40 cols,
and InspIRCd splits ISUPPORT across several lines.
Verified end to end against the live server: full InspIRCd MOTD (logo,
LUSERS, links) renders clean and stable; host unit tests cover color/
bold/CTCP-action stripping and prefix-less NOTICE/ERROR/PING.

irc HOST [NICK] - connects over the kernel TCP stack (DNS-resolves the
host), registers, and runs a live client on the 40x18 LCD.
UI, within the terminal's means (no cursor addressing - just \r + \b):
messages scroll above a fixed irssi-style input line '[#chan] text_'
redrawn in place; long input scrolls horizontally. The elders' formats:
<nick> msg, <nick:#c> off-channel, *nick* private, -nick- notice,
* nick action, >target< outbound, -!- server/status. Keys come from both
the OSK (SELECT) and the console ring (pollcon), so a hub can drive it.
Commands: /join /part /msg /me /nick /quit /raw, plus bare text to the
current channel. Handles PING (PONG + a wink), CTCP ACTION/VERSION,
JOIN/PART/QUIT/KICK/NICK, 332/353 topic+names, and 433 nick-in-use
(auto-appends _). Registers on bank 32 as program id 30.
Note: gbos doesn't zero C statics, so main() inits its state explicitly;
the local TCP port is randomized (DIV) to dodge a stale server-side
half-open from an unclean prior exit. Tested end to end against a small
ircd through gbhub: full MOTD burst, join, channel + private messages,
actions, and bot replies all render correctly.
