Description (first ~250 characters summarize the most important points — then longer explanation)
High Contrast Toggle instantly switches the current webpage into a high-contrast accessible view that increases readability by inverting backgrounds and enforcing clear foreground colors. It runs locally, uses only minimal permissions (activeTab, storage), and does not contact any remote servers.

This extension is a simple, privacy-preserving tool to help users read any page more comfortably. It injects a small stylesheet and toggles an HTML class so styles are applied without rewriting page markup. Settings are stored locally (link color) and no remote services are contacted. The add-on follows AMO rules: there are no inline scripts, no use of innerHTML, no remote code, and it requests only the permissions required to operate.
