| Style | Description |
|---|---|
| *Plain text* | Trend-colored text (green/red/grey) |
| *Split-flap board* | Airport board: white digit flaps, white € sign in the default font, cascading flip animation on price changes (configurable duration), trend LED |
| *Nixie tubes* | Retro amber glowing digits in glass tubes with configurable random flicker, white € sign in the default font, trend LED |
| *Split-flap board* | Airport board: white digit flaps, white € sign and a trend arrow in the default font. On a price change all flaps first reset to 0 (swept over ~2 s), then take their new values — the whole cycle spreads over the configured cascade time |
| *Nixie tubes* | Retro amber glowing digits in glass tubes with configurable random flicker, white € sign and a trend arrow in the default font |
In the split-flap and nixie styles the digits keep their display color and the
trend (up/down/unchanged) is shown on a small LED next to the display.
Display style changes apply immediately, without restarting the shell.
In the split-flap and nixie styles a trend arrow sits right of the € sign:
green ▲ when the price went up, red ▼ when it went down. When the price is
unchanged the last arrow stays; on the very first reading (and on API errors)
no arrow is shown. Display style changes apply immediately, without
restarting the shell.
| Situation | Plain text color | Trend LED |
| Situation | Plain text color | Arrow in flip/nixie modes |
|---|---|---|
| Price up | green | green |
| Price down | red | red |
| Price unchanged / first reading | grey | grey |
| API failure (network error, 4xx/5xx, rate limit 429) | `--` | grey |
| Price up | green | green ▲ |
| Price down | red | red ▼ |
| Price unchanged | grey | last arrow stays |
| First reading / API failure | grey / `--` | no arrow |
