🚀 SignBuilder v1.5 - The Storage & Display Studio Update

A massive feature and optimization update bringing advanced LCD storage tracking, custom playlist loops, smart survival blueprints, and major performance enhancements across Minecraft 1.20.1, 1.21.1, and 1.21.4!

📦 Storage Monitoring System & Storage Linker

• Storage Linker Item: Added the new Storage Linker tool (signbuilder:storage_linker) with a survival crafting recipe.
• Interactive Container Linking: Link chests, barrels, and containers to Modern LCD Screens with a simple right-click, accompanied by particle beams and audio feedback.
• In-World Chest Highlighting: Search for items in your storage network to highlight matching chests in 3D with glowing boxes, beacon beams, and distance indicators.
• Storage Search & Quick Pin: Interactive search bar with instant filtering, click-to-locate navigation, and Shift-Click support from the player inventory.
• 6 Storage Display Modes:
  • Top Items Grid: Clean visual overview of your most abundant items.
  • Capacity Gauge: Visual percentage bar showing current storage utilization.
  • Pinned Watchlist: Track specific items with custom pin/blacklist filters.
  • Throughput Monitor: Real-time inflow/outflow tracker (items per hour).
  • Activity Log: Chronological feed of recent deposit and extraction actions.
  • Compact Overview: Minimalist space-saving storage telemetry.

🎬 Visual Animation Loop & Step Text Studio

• Playlist & Loop Sequencer: Chain multiple animations and text slides into custom loops with sequential or randomized shuffle playback.
• Per-Step Customization: Set individual step durations (1–9999s), transitions (Cut, Fade, Slide, Zoom, Wipe), and custom accent colors.
• Step Text Studio: Add custom multi-line text slides directly into your animation loop.
  • Independent Line 1 & Line 2 inputs with customizable text animations (Scroll, Typewriter, Pulse, Blink, Static, etc.).
  • Dynamic live variables: {time}, {weather}, {player}, {day}, {dimension}, {fps}, and {health}.
  • Text styling shortcuts (Bold §l, Italic §o, Underline §n) and custom color swatches.
  • In-GUI real-time preview reflecting exact display output.
• Screen GUI Polish: Cleaned up interface lines, integrated RGB color sliders & HEX code inputs via Color Picker, and fixed text mode translations.

📐 Blueprint & Placement Upgrades

• Double-Sided Signs: Added full Front and Back face editing tabs with a one-click "Copy Front" action.
• Flexible Placement Directions: Full support for Left-to-Right, Right-to-Left and Forward.
• Hotbar Direction Cycling: Press Shift + Mouse Scroll while holding a blueprint to quickly cycle placement directions without switching hotbar slots.
• Survival Material Pre-Check: Scans your inventory before stamping. If any letters, backplates, or materials are missing, placement pauses and displays a clear, localized missing items list in chat.
• Whitespace Fix: Resolved a bug that stripped leading/trailing spaces during vertical banner placement.

🎨 Rendering & Visual Polish

• Silk-Touched Item Rendering (1.21.4): Letters, numbers, and backplates mined with Silk Touch now retain their applied RGB colors, rainbow flow, and materials in the player inventory, hotbar, third-person hand, and world item drops.
• Button Hold Animation: Added an arm push/hold pose when holding down interactive button blocks.
• LCD Artifact Fixes: Eliminated corner jittering/trembling artifacts on LCD screens and resolved character box artifacts on backplate status text.
• Frustum Culling Stability: Resolved flickering and wall block popping when viewing signs and screens from acute camera angles.
• Grid Placement Protection: Prevented accidental overwriting when placing grid characters onto occupied backplates.

⚡ Performance & Memory (RAM / GC) Optimizations

• Backface Culling: Immediately skips all rendering, vertex generation, and matrix transformations when viewing LCD screens from behind (dot <= 0.0).
• Distance LOD: Added a 96-block render cutoff for LCD screens and a 36-block LOD threshold to skip rendering heavy 3D item stacks inside storage screens.
• Zero-Allocation Font Caching: Implemented a direct-mapped 64-entry font width cache and entity bounding box caching, significantly reducing transient garbage collection (GC) stutter.
• Ticker & Ghost Optimizations: Disabled unnecessary client-side block entity tickers for static signs and cached preview hologram quads for silky smooth blueprint placement.

🌐 Quality of Life & Engine Updates

• Smart Turkish 'İ' / 'i' Case Conversion: Client-language-aware capitalization converting 'i' to 'İ' for Turkish locale while preserving standard 'I' for other languages.
• 1.21.4 Recipe Syntax Migration: Migrated all recipes to modern Mojang HolderSet syntax.
