//! 6 named `ColorScheme` constructors.
//!
//! All 19 fields with legacy counterparts (`background`, `foreground`,
//! `primary`, `accent`, `muted`, `border`, `user_bg`, `response_bg`,
//! `thinking_bg`, `success`, `warning`, `error`, `code_bg`, `selection_bg`,
//! `surface_bg`, `panel_bg`, `diff_add_bg`, `diff_remove_bg`, `diff_hunk_bg`)
//! use the exact RGB triple from `oxi-tui-legacy/src/theme.rs`.
//!
//! The 9 fg slots that the legacy did not model (`user`, `response`,
//! `thinking`, `tool`, `tool_bg`, `info`, `diff_add`, `diff_remove`,
//! `diff_hunk`) are derived from the closest legacy analog:
//!
//! | new slot     | derived from (legacy)        | rationale                  |
//! |--------------|------------------------------|----------------------------|
//! | `user`       | `user_border`                | matches primary accent     |
//! | `response`   | `foreground`                 | default body text          |
//! | `thinking`   | `muted`                      | dimmed reasoning text      |
//! | `tool`       | `muted`                      | tool headers are dimmed    |
//! | `tool_bg`    | `tool_pending_bg`            | subtle tool call bg        |
//! | `info`       | `secondary`                  | legacy's blue-green accent |
//! | `diff_add`   | `success`                    | green = added line         |
//! | `diff_remove`| `error`                      | red = removed line         |
//! | `diff_hunk`  | `muted`                      | subtle hunk header         |
