LangChain brand colors and semantic constants for the CLI.
Single source of truth for color values used in Python code (Rich markup,
Content.styled, Content.from_markup). CSS-side styling should reference
Textual CSS variables: built-in variables
($primary, $background, $text-muted, $error-muted, etc.) are set via
register_theme() in DeepAgentsApp.__init__, while the few app-specific
variables ($mode-bash, $mode-command, $skill, $skill-hover, $tool,
$tool-hover) are backed by these constants via App.get_theme_variable_defaults().
Code that needs custom CSS variable values should call
get_css_variable_defaults(dark=...). For the full semantic color palette, look
up the ThemeColors instance via ThemeEntry.REGISTRY.
Users can define custom themes in ~/.deepagents/config.toml under
[themes.<name>] sections. Each new theme section must include label (str);
dark (bool) defaults to False if omitted (set to True for dark themes).
Color fields are optional and fall back to the built-in dark/light palette based
on the dark flag. Sections whose name matches a built-in theme override its
colors without replacing it. See _load_user_themes() for details.
