Align zone textures with each theme's palette identity:
- Fabric: linen weave in navy/steel tones (was generic green/blue/red/gray)
- Leather: grain texture in warm brown/amber tones
- VelvetMarble: smooth charcoal marble veining (replaces .jpg with .png)
All zones now have dark + light scheme variants for OS color scheme
adaptation. Plasma zones deferred to separate iteration.
Address PR review:
- Add theme.cfg ([Style] Name = Fusion, ColorScheme = System) to Fabric,
Leather, Plasma and VelvetMarble so their curated palettes actually apply.
Without it the native style paints button chrome from the OS (windowsvista
on Windows has no dark mode), making the dark palettes' light ButtonText
unreadable on light buttons.
- Leverage the scheme-variant asset resolution: register home-dark.png and
home-light.png in resources and add them to the qrc so the built-in home
background also flips with the palette instead of staying static.
- Fix Leather [Palette.Inactive] Accent, which copied the Active Highlight
color instead of the theme accent (dark #4a5f8f -> #c9995a, light
#34508c -> #a5712f) in both palette files.
The Fabric, Leather, Plasma and VelvetMarble themes shipped only zone art and no palette, so their chrome fell back to the bare OS palette. Each theme now ships light and dark curated defaults written in the palette editor's own conventions, with [AppColors] so the home-tab buttons keep the theme's identity over static backgrounds.
- Add palette-default-light.toml / palette-default-dark.toml for the four themes; scheme resolution follows the OS since the themes declare no color scheme.
- Tint the window/base/button chrome and bevels towards each theme's identity: navy cloth (Fabric), black-brown with brass accents (Leather), electric violet with cyan sparks (Plasma), charcoal velvet with slate marble (VelvetMarble).
- Fill [AppColors] AccentStrong / AccentSoft per theme so the home-tab button gradient matches instead of falling back to the default greens.
- Derive Disabled and Inactive groups with the same conventions as PaletteGenerator::fromAccent.
