📘 Reading Ruler — Minimal, Accessible On‑Page Reading Aid

Reading Ruler is a lightweight, keyboard‑driven accessibility tool that helps users maintain focus while reading long pages of text.

It adds a subtle highlight “ruler” that follows the cursor and dims the rest of the page, improving readability without clutter or UI bloat.

This extension is built to be:

• Minimal — no popup, no options page, no UI chrome
• Fast — pure content script, no frameworks
• Accessible — adjustable height, dim strength, and brightness
• Keyboard‑first — every feature is controlled by shortcuts
• Privacy‑first — no data collection, no external requests
