//! # WSG Library — Public API Surface
//!
//! Re-exports all submodules so consumers can access types via `wsg::mesh::Mesh`, etc.
//! The library's core responsibility is to abstract five wgpu objects (Instance, Surface, Adapter, Device, Queue)
//! into a single Context for simpler user interaction.
//!
//! ## Module Interactions
//! - **context** owns hardware resources (Device, Queue, Surface) across the frame lifecycle.
//! - **pipeline_cache** compiles WGSL shaders into RenderPipelines once, caching them via HashMap + Arc.
//! - **material** requests pipelines from PipelineCache to define per-object appearance.
//! - **mesh** holds vertex/index buffers sent to the GPU once at creation time.
//! - **renderer** orchestrates draw calls using Material + Mesh references passed in at render time.
//! - **vertex** defines the CPU-side vertex layout matching GPU shader input attributes.
//! - **error** provides application-level error types mapping each failure mode to a message.
//! - **conf** centralizes shared constants like shader paths and embedded fallback sources.
