on GitHub

Adds software updates, one-click rollback, and theme switching to the on-TV Dashboard App (#155), along with WCAG AA accessibility contrast improvements and native static font support for webOS 4.

New Features

• Software Updates & Rollback from TV Screen (#155):
  • Dedicated Updates Tab: Added an Updates tab to the on-TV dashboard app (dashboard.html).
  • Check & Install Releases: View current version, query GitHub for new releases, and install updates in-place directly from the couch using the Magic Remote.
  • One-Click Rollback: Automatically backs up previous versions to /var/lib/tvweb/.previous/ with immediate one-click rollback capability.
  • Safety Confirmation: Two-step remote confirmation ("Confirm? Press OK again to install...") prevents accidental triggers.
  • Live Restart Polling: In-progress monitoring polls /api/update until the Node.js server finishes restarting and reloads the interface seamlessly.
  • System Tab Shortcut: Added Dashboard Server row in the System tab for instant access to the Updates tab.
• On-TV Appearance & Theme Toggle:
  • Added a Theme toggle (Dark / Light) under an Appearance section in the System tab.
  • Persists user preference in TV localStorage without requiring CSS custom properties (compatible with Chromium 38).
  • Fast, flicker-free theme switching between true OLED black (#000) and high-contrast Light mode (#f5f5f5).

Enhancements & Fixes

• Accessibility & Contrast Uplift (WCAG 2.1 AA):
  • Uplifted opacity steps across all inactive tabs, row labels, values, and section headers from ~1.5:1 / 2:1 up to 5.2:1–8.5:1 contrast ratios.
  • Completely eliminates dim, hard-to-read text from sofa distances while preserving visual hierarchy for selected rows.
• Static Font Compatibility for webOS 4 / B8:
  • Generated dedicated static TrueType instances (Outfit-Light, Outfit-Regular, Manrope-Regular, Manrope-SemiBold) with --no-overlap to satisfy legacy OpenType Sanitizers.
  • Bypasses Chromium 38's lack of OpenType Variable Font support (which previously locked text to hairline 100/200 weights), delivering solid 300/400 stem thickness that upscales cleanly to 4K displays.
