//! Unified style module for consistent theming and styling across all plot types
//!
//! This module consolidates all styling-related types and utilities that were
//! previously scattered across `render` and `core` modules. It provides a
//! single import point for all styling needs.
//!
//! # Organization
//!
//! The style module re-exports types from their original locations for
//! backward compatibility, while providing a unified namespace:
//!
//! - **Colors**: [`Color`] - RGB/RGBA color representation
//! - **Themes**: [`Theme`] - Complete plot theming
//! - **Line styles**: [`LineStyle`] - Solid, dashed, dotted, etc.
//! - **Marker styles**: [`MarkerStyle`] - Circle, square, triangle, etc.
//! - **Grid styles**: [`GridStyle`] - Grid line configuration
//! - **Plot styles**: [`PlotStyle`] - High-level style presets
//! - **Style resolution**: [`StyleResolver`] - Theme-aware style resolution
//!
//! # Example
//!
//! ```rust,ignore
//! use ruviz::style::{Color, Theme, LineStyle, MarkerStyle, GridStyle};
//!
//! // Create a custom theme
//! let theme = Theme::dark();
//!
//! // Use style presets
//! let style = PlotStyle::Publication;
//!
//! // Configure grid appearance
//! let grid = GridStyle::default()
//!     .color(Color::LIGHT_GRAY)
//!     .alpha(0.3);
//! ```
//!
//! # Migration from Previous Imports
//!
//! Previous import paths continue to work:
//! ```rust,ignore
//! // Old paths (still work)
//! use ruviz::render::{Color, Theme, LineStyle, MarkerStyle};
//! use ruviz::core::{GridStyle, PlotStyle, StyleResolver};
//!
//! // New unified path (recommended)
//! use ruviz::style::{Color, Theme, LineStyle, MarkerStyle, GridStyle, PlotStyle, StyleResolver};
//! ```
