SkiaSharp 4.0 — animated font screenshots

A self-contained .NET 10 file-based app that renders two looping animated WebPs for the "SkiaSharp 4.0 is here" blog post, using the 4.148.0 NuGet packages. Each image showcases a new v4 capability, and the act of encoding them exercises a third (the animated WebP encoder).

Output	Shows	v4 features
`skiasharp-variable.webp`	The word SkiaSharp in Inter Variable, its `wght` axis morphing 100 → 900 → 100	Variable-font axes via `SKTypeface.Clone(font variations)` + animated WebP
`skiasharp-color.webp`	v4 in the Nabla COLR/CPAL color font, cycling all 7 palettes	Color-font palettes via `SKTypeface.Clone(paletteIndex)` + animated WebP

The Perfect Navigation System for .NET MAUI

What Would It Look Like If We Started From Scratch?

This document compares navigation systems across platforms and frameworks, identifies what each gets right and wrong, and proposes what a ground-up replacement for MAUI navigation would look like. The goal is to design the ideal system first, then layer backward compatibility on top — not the other way around.

Deep Research: Decoupling SkiaSharp's Public API From Skia

Context: This is a research-driven response to a thought experiment proposing that SkiaSharp should evolve from a 1:1 Skia mirror into a "Skia-inspired but independently versioned" API. Five parallel research agents investigated the actual codebase, tooling, consumer impact, and creative alternatives.

✅ What I AGREE With

1. "Churn is concentrated, not pervasive" — Verified, mostly.
