Speed Reader - RSVP Fast Reading

단일 목적

Single purpose: Display the current page's article text, or the user's selected text, as a one-word-at-a-time (RSVP) speed-reading overlay. Permission — activeTab: Used to access the current tab only when the user activates the reader (toolbar click, keyboard shortcut, or right-click menu), so the overlay can read the text to display. Permission — scripting: Used to inject the reader overlay (reader.js / reader.css) into the active tab on demand. No content scripts run automatically. Permission — storage: Used only to remember the user's chosen reading speed (chrome.storage.local). No personal data stored. Permission — contextMenus: Used only to add the "Speed read selection" right-click option. Host permissions: None. No host_permissions and no <all_urls>; page access is granted only at the moment of activation via activeTab. Remote code: None. All code is bundled in the package; nothing is fetched or eval'd at runtime. Data collection / transmission: None. No data is collected, stored off-device, or transmitted. All processing is local.
