FontShifter од Amir Esfandiyari

FontShifter changes the font of any website — with per-site or global control.

Pick from three beautiful bundled fonts (Dana, IRANSans, Vazir) and apply them to
the site you're on, or set one as the default for every site. A per-site choice
always overrides the global default.

Features
- 🎨 Bundled Persian fonts, applied with one click — no downloads.
- 🌍 Per-site or global settings.
- ↔ Independent right-to-left (RTL) toggle — change the font without flipping
layout direction, or flip direction without changing the font.
- ⚡ Works on modern single-page apps, web components, and Shadow DOM
(Claude.ai, ChatGPT, and similar sites).
- 🔒 CSP-safe: uses Constructable Stylesheets and extension-hosted fonts, so it
never strips security headers.

All settings are stored locally on your device. FontShifter does not collect,
transmit, or sell any data.
