Added new themes aswel as new seasonal themes.
Added syllable per syllable advancements.
Improved ui/ux

TTS beta-lock - HUD speaker button greys out with a lock icon, Advanced page's read-aloud controls are disabled with a "Beta, coming soon" badge, and pressing M (or clicking it) shows a small toast instead of doing nothing. Locked at three points in the code (the toggle, the session-start seed, and speakSegment itself) specifically so a preference someone saved before this existed can't sneak through.

Multi-page Settings - Settings, Keybinds, Themes, and Advanced, each their own page, sharing common logic through a new shared.js instead of duplicating it four times. This is the foundation for everything else in feature-list.txt that's coming to Keybinds and Themes specifically.

Three new supporter presets - OLED Black, Cyberpunk, Vintage Sepia join Aurora and Rose Gold at the any-supporter tier.

Two new opt-in/opt-out toggles on Advanced: show/hide the floating HUD, and auto-scroll on/off.

Pacing quick-presets - Slow/Normal/Fast buttons above the WPM slider.

Custom colors gated to supporters - the free color pickers now lock the same way the Aurora/Rose Gold presets already did, with the inputs visually dimmed and disabled when there's no active code.

Tiered supporter system - any supporter (one-time or subscriber) unlocks Aurora, Rose Gold, and custom colors. A new Nebula preset plus a pulsing HUD glow are exclusive to subscriber status specifically. The popup badge and toolbar icon now show a distinct double-heart mark for subscribers vs the single heart for one-time supporters, and both fall back gracefully to free defaults if a subscription lapses.

Exact Selection mode - new Selection Scope control in the popup and Settings: "Expand to paragraph" (unchanged default) or "Exact selection only," which uses just what you highlighted. This is functional, not cosmetic, so it's free for everyone, in keeping with the same principle the whole Supporter Program was built on. Needed a real architectural change: sessions now build from either a container element or a range-clipped walk that trims the two boundary nodes to exact offsets, and I refactored the shared session-start logic so both paths (native and Isolated Reader View) go through one core function.

📑 Release Notes - v1.3.1
🛠 Bug Fixes & Improvements
Cross-Browser Service Worker Support:
Updated background script configuration to seamlessly support both Chromium (Chrome/Edge) and Gecko (Firefox/Zen Browser) extension architectures.
Replaced top-level script loading with a universal globalThis configuration pattern to prevent module scope crashes across engines.
Supabase API Authentication:
Updated redemption code RPC requests in background.js to ensure compatibility with Supabase's new publishable key standard (sb_publishable_...).
Extension Messaging Resilience:
Resolved Receiving end does not exist context invalidation errors during Ko-fi code activation in the Options/Settings tab.

Added:
Reading Analytics - a floating HUD shows live word count + estimated reading time whenever a session is active
Auto-Advance pacing - press P (or the HUD's play button) to step through at a target WPM you set in Settings
Text-to-Speech - press M to have it read aloud, synced with the highlight; when both TTS and auto-advance are on, stepping is paced by the voice finishing each segment rather than a timer
Reading History - opt-in, viewable and clearable in Settings → History & Progress
Progress Tracking - on by default; a small "Resume reading?" banner appears when you revisit a page you'd been stepping through
