A full-screen terminal news ticker that renders live global headlines in large OTF-font block characters with a white-hot → deep green gradient. Headlines auto-translate into the native script of their subject region. Ambient mic input warps the glitch rate in real time. A `--poetry` mode replaces the feed with public-domain literary passages. Live messages can be pushed to the display over [ntfy.sh](https://ntfy.sh).

To add your own fonts, drop `.otf`, `.ttf`, or `.ttc` files into `fonts/` (or point `--font-dir` at any other folder). Font collections (`.ttc`, multi-face `.otf`) are enumerated face-by-face.
### Color Schemes
Mainline supports three color themes for the scrolling gradient: **Verdant Green**, **Molten Orange**, and **Violet Purple**. Each theme uses a precise color-opposite palette for ntfy message queue rendering (magenta, blue, and yellow respectively).
On startup, an interactive picker presents all available color schemes:
```
[1] Verdant Green (white-hot → deep green)
[2] Molten Orange (white-hot → deep orange)
[3] Violet Purple (white-hot → deep purple)
```
Navigation: `↑`/`↓` or `j`/`k` to move, `Enter` or `q` to select. The selection applies only to the current session; you'll pick a fresh theme each run.
**Note:** The boot UI (title, status lines, font picker menu) uses a hardcoded green accent color for visual continuity. Only the scrolling headlines and incoming messages render in the selected theme gradient.
### ntfy.sh
Mainline polls a configurable ntfy.sh topic in the background. When a message arrives, the scroll pauses and the message renders full-screen for `MESSAGE_DISPLAY_SECS` seconds, then the stream resumes.
