//! Elegance — opinionated, beautiful widgets for egui.
//!
//! Elegance is a small companion crate to [`egui`] that provides a cohesive
//! design system inspired by modern web UIs: chunky rounded buttons in a
//! handful of accent colors, crisp inputs with a focus ring, pill-shaped
//! status indicators, cards, tabs, segmented buttons, and a matching colour
//! palette. Four palettes ship built-in — two dark
//! ([`Theme::slate`] and [`Theme::charcoal`]) and two light
//! ([`Theme::frost`] and [`Theme::paper`]) — paired so you can toggle without
//! a layout shift.
//!
//! # Getting started
//!
//! ```no_run
//! use eframe::egui;
//! use elegance::{Theme, Button, Card, Accent};
//!
//! fn main() -> eframe::Result<()> {
//!     eframe::run_ui_native(
//!         "elegance demo",
//!         eframe::NativeOptions::default(),
//!         |ui, _| {
//!             Theme::slate().install(ui.ctx());
//!             egui::CentralPanel::default().show_inside(ui, |ui| {
//!                 Card::new().heading("Hello").show(ui, |ui| {
//!                     if ui.add(Button::new("Click me").accent(Accent::Blue))
//!                         .clicked()
//!                     {
//!                         println!("clicked!");
//!                     }
//!                 });
//!             });
//!         },
//!     )
//! }
//! ```
//!
//! # Design
//!
//! All visuals are driven by a [`Theme`] value. Calling [`Theme::install`]
//! once at startup configures [`egui::Style`] so that built-in widgets
//! (labels, sliders, etc.) inherit the elegance look, and it stores the
//! theme in `ctx` memory so elegance widgets can pick it up automatically.

pub use egui;

/// Request a repaint such that the next paint comes ~`1/hz` seconds from now,
/// independent of display refresh rate.
///
/// [`egui::Context::request_repaint_after`] internally subtracts `predicted_dt`
/// from the requested delay to budget for the paint taking time. On a 60 Hz
/// integration (egui's default) that subtraction is ~16.7 ms, so a naive
/// `request_repaint_after(1/30 s)` lands on the very next vsync and produces
/// ~60 Hz — double the rate you asked for. This helper adds `predicted_dt`
/// back in so the effective cadence lands near `1/hz` on any refresh rate.
///
/// Typical use: throttle continuously-animating widgets (spinners, progress
/// fills) to 20–30 Hz so they don't burn a full vsync budget on motion the
/// eye can't resolve.
