LED digital coolers that came up a dim, colourless "888" now display properly. Single-display LED digital coolers (AX120, frozen-horizon/magic, LF15, LF13, CZ1 and similar) could show dim grey with no colour even though the numbers were correct. The cause was a leftover "test mode" flag that got saved into your config in an earlier session and was silently restored on every launch. Test mode is a momentary diagnostic now — it never persists across restarts — so your colours come back. Its reference colours are also full-bright now, and it applies to the multi-zone coolers too.
Metric text renders at the right size, and fan speeds show again. Large authored metric sizes (like a big hero temperature) were being shrunk to a small default; they now render at their intended size. Fan-RPM tiles that previously drew nothing now show the speed.
Show or hide the unit on each metric. Every metric element can draw its value with the unit (45°C, 60%, 1200 RPM) or as a bare number when the unit is already part of the theme art — a per-element toggle in the editor, the CLI (`--show-unit` / `--hide-unit`) and the API. Celsius/Fahrenheit stays where it has always been, on the About panel.
