v1.3.3 — UI Polish & Navigation Overhaul

What's new in v1.3.3

Navigation & Layout

• Floating app bar on Gallery and Albums — content now scrolls visibly underneath with a gradient fade, matching the bottom pill bar style
• Segmented pill control replaces the separate tab buttons — a single dark toggle between All and Album views, consistent across both pages
• Gallery title moved to the left edge (was incorrectly centered)

Visual Improvements

• Splash screen — "SnapTune" title is now centred and larger (54px), tagline pinned to the bottom
• Circular icon button — the ⋮ menu button now has a proper circle shape instead of a squircle
• Light mode viewer — viewer background now correctly follows the theme (was stuck on black)

Optimize & Result Pages

• Back button added to the Optimize page when opened from the media viewer
• Result page redesign — removed the generic AI success icon; now shows platform name, a green "Ready" chip, and a real before/after file size comparison

Fixes

• Removed unused dart:ui and share_plus imports
• Cleaned up unused _scaleAnim animation field from result page
