Overview

Prisma is a modern, privacy-focused, resource-optimized multimedia application engineered with Flutter. It unifies dozens of popular booru imageboards, artwork archives, manga platforms, and light novel repositories into a fluid Material 3 interface across mobile and desktop environments.

Built from the ground up for low latency, smooth 60/120 FPS navigation, and predictable memory footprint, Prisma handles multi-gigabyte media collections without interface stutter or out-of-memory crashes.

⚡ Key Highlights

• Proactive Feed Prefetching: Intelligent viewport preloading buffers subsequent media pages seamlessly ahead of scroll velocity.
• Hardware-Accelerated Video Engine: Integrated media_kit (libmpv) player tuned for minimal Time-to-First-Frame (TTFF) and low-latency WebM/MP4 playback.
• Extensive Ecosystem: Native support for over 15 imageboards, manga scanlations, light novel libraries, and creator networks.
• Deterministic Sliding-Window Memory: Aggressive $\pm 1$ page eviction isolates memory consumption to active viewports.
• Live Network Diagnostics: Monotonic hardware stopwatch RTT measurements, streaming health telemetry, and automatic offline fail-safe.
• Adaptive Glass UI & Layouts: Customizable navigation rail (Left / Right / Bottom), AMOLED black, and Liquid Glass Material 3 themes.

🚀 Core Capabilities

📱 Media & Feed Browsing

• Adaptive Viewport Modes: Continuous Pinterest-style masonry grid, 1:1 square cards, and dense compact lists.
• Dynamic Resolution Profiles: Configure image fidelity per environment — Auto, Data Saver / Preview, Sample / Balanced, or uncompressed Original.
• Deep Zoom & High-Fidelity Viewer: Multi-touch interactive zoom, pan gesture physics, asset variants switcher, and Danbooru-style translation notes overlay.
• Post Sets & Manga Navigation: Multi-page artwork indicator on feed cards and dedicated bottom page-stepper strip for sequential works.

📚 Manga & Light Novel Hub

• Integrated Global Catalogs: Instant streaming and reading from MangaDex, MangaLib, and RanobeLib.
• Specialized Reading Pipelines:
  • Webtoon Mode: Frictionless continuous vertical strip with hardware-accelerated image decoding.
  • Manga Reader: Traditional Right-to-Left (RTL) and Left-to-Right (LTR) page layouts with custom margin tuning.
  • Light Novel Typography: Dedicated formatting engine with adjustable typeface, font size, line spacing, and eye-friendly color themes.
• Reading Progress Synchronization: Automated bookmarking, unread tracking, and library organization (Reading, Plan to Read, Completed, On Hold, Dropped).

🔍 Search & Intelligent Filtering

• Sub-Millisecond Tag Autocomplete: Instant token suggestions queried across millions of booru tags.
• Advanced Query Syntax: Multi-tag search, boolean exclusion (-tag), explicit and conjunctions, and source switching without resetting query parameters.
• Three-Tier Content Control: Flexible blacklist, whitelist, NSFW auto-blur, and quick toggle between Safe and Unrestricted modes.
• Creator Hub: Direct author profiles, portfolio browsing, and creator archive indexing.

🛡️ Resource Optimization & Diagnostics

• Smart Memory GC & Watchdog: Proactively intercepts OS low-memory warnings, releasing decoded raster surfaces before memory thresholds trigger process termination.
• Sliding-Window Eviction: Ensures carousel memory bounds never exceed active neighbors ($\pm 1$), evicting distant decoders.
