## What it is
wob is a lightweight overlay bar for Wayland compositors that displays values like volume or brightness as a transient on-screen indicator. It reads numbers from stdin or a named pipe and renders them using the wlr_layer_shell protocol.

## Use cases
- show a volume bar when changing audio level on sway
- display a brightness indicator when adjusting backlight
- visualize any numeric value fed via a named pipe
- get an OSD-style feedback bar on Wayland like xob on X11

## When to choose
- you use a wlroots-based Wayland compositor like sway and want a minimal OSD bar
- you want a tiny, scriptable indicator driven by shell scripts or keybindings
- you prefer a lightweight C tool over notification-daemon hacks

## When to avoid
- you are on X11 (use xob instead)
- you need icons or rich OSD features (consider avizo or SwayOSD)
- your compositor lacks wlr_layer_shell support
