 ## features
 
-* **Mirrored Braille Waveform**: Download above the axis, upload below, rendered on a 2x4-dot braille canvas with a smooth interpolated crest
-* **Big Block Digits**: 5x5 bitmap hero numbers (timr-tui technique) — chunky enough to read at a glance, tabular so they never jitter
-* **Calm Motion**: Spring-driven value easing, an idle breathing pulse, a burst ripple, a pulsing link dot, a 180ms theme crossfade, and a skippable launch sequence — all disabled by `--no-anim`
-* **Time Windows**: `w` cycles 1m / 5m / 15m / 1h / 24h
-* **Scale Modes**: `S` cycles auto / linear / sqrt; `G` toggles the faint midpoint gridline
-* **Snapshot Export**: `s` writes the current frame as `.ansi` and `.txt`
-* **11 Built-in Themes**: `default`, `nord`, `dracula`, `gruvbox`, `forest`, `monochrome`, `catppuccin`, `tokyo-night`, `rose-pine`, `kanagawa`, `ansi`
-* **Custom TOML Themes**: Load custom color schemes from your config directory (see [docs/themes.md](docs/themes.md))
-* **Text Streams First**: `--json`, `--json-stream`, and `--format` (see [docs/json.md](docs/json.md))
-* **No telemetry**: The only network call flow makes is a latency probe to your configured ping target
-* **Cross-Platform**: Linux, macOS, and Windows, on amd64 and arm64, built without cgo
-* **Pipes cleanly**: Not a TTY means a single plain line, so status bars never receive escape codes
