- Enter alternate screen buffer (\x1b[?1049h) before drawing and exit
it (\x1b[?1049l) on cleanup. This preserves the user's terminal
content when the app quits.
- Clear screen once after entering alt buffer so drawing starts from
the top-left.
- Add -h and --help flags that print usage, stdin/file modes, and
controls (q / Ctrl-C to quit).
- Update tests for new alt-buffer helpers and help text.
- Rebuild CLI bundle (dist/qr-terminal.js 95.4kb) and redeploy webapp.
- Stop clearing the entire screen every frame — now clears once on first
draw, then uses cursor-up (\x1b[nA) to overwrite the QR block in place.
- Removed frame counter, generation info, and 'press q' text — only the
QR code is shown, keeping the display minimal and static-area free.
- Simplified buildFrames return type (Uint8Array[] only).
- Added moveCursorUp() helper to terminal_raster.ts.
Terminal block characters render in the foreground colour; on dark-themed
terminals the QR looked inverted. Now every line is wrapped with
\x1b[47m\x1b[30m (white bg / black fg) so dark modules appear black and
light modules appear white on any terminal theme.
- renderToTerminal now pads with a 4-module quiet zone (white border)
horizontally and vertically, matching the webapp rasterizer.
- Keyboard input now tries /dev/tty first so q/Ctrl-C works even when
stdin is a pipe (e.g. echo ... | bun run src/cli/qr-terminal.ts).
- Update all CLI renderer tests for padded output; add tests for custom
and zero quiet zone.
- Increase outer_ec_benefit test timeout to 15s to avoid flaky failures.
- Rebuild CLI bundle and webapp; redeploy to nginx.
