Keys of the two scrolling tab-indicator maps that cross the daemon → KWin effect boundary on org.plasmazones.Tiling: the per-screen context-rule PAINT override map (scrollTabPaintOverridesChanged / scrollTabPaintOverrides, all eleven paint keys) and the per-window rule COLOUR map (scrollTabColors / scrollTabColorsChanged, the three colour keys).
The daemon produces them (src/dbus/windowtrackingadaptor/internal.h's WindowPaintKeys / WindowColorKeys forward to these) and the effect's TilingHandler reads them; this is the ONE home for the spellings, so a rename is a compile error on both sides rather than a silently dropped override. The XML DocStrings in dbus/org.plasmazones.Tiling.xml (and a few C++ doc comments) repeat the spellings as prose only.
