The `viz` command is enabled, but the `viz_static` tier is not. `qsv viz` and
`qsv viz smart` produce self-contained interactive HTML, which is the primary
output format. Static image export (`-o chart.png`, `.svg`, `.pdf`, `.jpeg`,
`.webp`) is unavailable on this prebuilt and will report that qsv was not built
with `viz_static`.

`viz_static` drives a headless Chromium/Firefox via an auto-downloaded webdriver,
and building it does not complete inside GitHub's Action Runner job limit on
Windows. Compile qsv natively on this platform with `--features viz_static` if
you need static image export.
