Description

Version bump and behavioral fixes for Twitch ad-blocking scripts (vaft-ublock-origin.js v84→v85) and regenerated dist/resources.json.

Key changes:

1. Post-ad re-entry guard for snapshot replay: prevents stale clean-playlist snapshots from being replayed when a consecutive ad break starts within 8s of the previous reload.
2. iOS/iPadOS soft-reload downgrade: detects Apple touch devices and downgrades hard reloads to soft reloads to preserve the user-gesture-blessed media element, avoiding black-screen + play-icon stalls.
3. Hidden-tab backoff exception during ad breaks: stops throttling the buffer monitor poll rate (3× slower) while an ad break is active on a backgrounded tab, preventing "stuck loading until refocus" stalls.

Security Hotspots

1. isAppleTouchDevice detection via navigator.platform/navigator.maxTouchPoints — purely informational client-side check, no data exfiltration. Low risk.

Changes

Changes

resources/vaft-ublock-origin.js

• Version bump 84 → 85
• stripAdSegments: added recentReloadReentry guard — skips snapshot replay if LastPlayerReload was <8s ago
• New isAppleTouchDevice IIFE — detects iPhone/iPad/iPod or iPadOS 13+ (MacIntel + touch)
• New iosSoftReload flag — reads twitchAdSolutions_iosSoftReload from localStorage, defaults true on Apple touch
• doTwitchPlayerTask: hardReload now ANDs with !iosSoftReload; logs downgrade when active
• monitorPlayerBuffering: shouldThrottle condition now includes && !playerBufferState.inAdBreak

dist/resources.json

• Regenerated single-line JSON containing all base64-encoded resources including updated vaft-ublock-origin.js
