Struct ThemeConfig 

pub struct ThemeConfig {
    pub preset: Option<String>,
    pub overrides: BTreeMap<String, String>,
}

[theme] block (issue #33) — role-based TUI colour scheme.

Two knobs:

• preset (optional string) — pick a built-in palette (catppuccin, gruvbox, tokyo-night). When absent, the resolved theme starts from crate::tui::theme::Theme::default (the pre-#33 hardcoded scheme).
• Per-role keys (focus, accent, branch, …) — override the colour of a single role on top of the preset (or default). Recognised colours: named (cyan, bright_blue), indexed (220), or hex (#89b4fa).

Validation runs in Config::load_for_repo via Self::resolve, so unknown presets, unknown roles, and bad colour values fail at load instead of silently picking the default colour at render time.

Fields

preset: Option<String>

Optional preset name. None → start from the default scheme. Some("catppuccin") → seed every role from that preset.

overrides: BTreeMap<String, String>

Per-role overrides. Keys must match an entry in crate::tui::theme::Theme; values must parse via crate::tui::theme::parse_color.

Implementations

impl ThemeConfig

pub fn resolve(&self) -> Result<Theme>

Resolve this config into a crate::tui::theme::Theme:

1. Start from the preset if any (else default).
2. Apply every per-role override on top.

Returns Err(GwmError::Config(_)) on unknown preset, unknown role, or bad colour value.
