Axis — the Vox GUI product brand

Axis (full brand Vox Axis) is the product name of the Vox GUI. It launches via vox axis (a clap alias of vox gui) and renders “Axis” in the window title and sidebar mark, with “Vox Axis” spelled out in the footer.

Naming convention: display/prose = “Vox Axis” or “Axis”; identifiers/commands/files = axis / VoxAxis. On first mention in a file, write “Vox Axis (Axis)”.

Deliberately unchanged (brand-layer only): the vox-gui crate name, the vox binary, vox-gui.exe, tauri.conf.json productName (“Vox”) and identifier (org.vox-foundation.gui). Renaming those is an out-of-scope follow-up.
