CURATED CONTENT
• 120 deep interview tickets across 15 topics: ownership, lifetimes, async, traits, smart pointers, concurrency, error handling, macros, unsafe, FFI, pattern matching, stdlib, ecosystem, and more — bilingual EN/RU
• 10 long-form System Design walkthroughs at senior level: distributed rate limiter, matching engine, distributed cache, time-series DB, crypto wallet custody, WebSocket pub/sub, distributed job queue, trade settlement, search index, multi-region KV store — bilingual
• 5 Mock interview scenarios (5 questions each) with progressive hints, red-flag indicators, strong-answer reveals, and rubric scoring — bilingual
• 10 Cheatsheet cards: compact reference for ownership, lifetimes, common traits, error handling, async, pattern matching, smart pointers, iterators, modules, tools
• 61 Glossary terms A–Z with bilingual definitions and Rust code examples (Arc, Box, Cow, Future, Pin, Mutex, …)
• 6 Tutorial series with sequential lessons: Ownership 101, Borrowing & References, Lifetimes 101, Error handling, Iterators & closures, Async Rust intro — progress tracked per lesson
• 28 Editor snippets — common Rust patterns (fn main, async fn, builder, thiserror enum, impl Iterator, tokio::select!, …)
• 49 in-app FAQ entries explaining every feature

LEARNING MECHANICS
• Spaced Repetition (Leitner-5: 1/3/7/14/30-day intervals)
• Quiz with 4 modes: SRS due-tickets, your Bookmarks, category+level Filter, or Glossary terms
• Practice mode — flashcard review without affecting your SRS schedule
• Day streak with daily-goal protection (configurable target: 5/10/20/30 events)
• Activity heatmap — 12 weeks of study density
• Statistics dashboard with per-category mastery, tutorial progress, recent activity

PERSONAL ORGANIZATION
• Bookmark any ticket, walkthrough, or mock — cross-content list
• Personal notes (up to 4000 chars) with search + centralized view
• Backup/Restore via JSON file — move progress between devices, no cloud

CODE EDITOR
• Rust syntax highlighting
• Basic lint markers (balanced brackets, quote pairs)
• Auto-save with 2-second debounce
• Snippet picker — 28 patterns across Common / Async / Errors / Traits / Macros / Tests categories

PRIVACY
• Everything is local — your progress lives in on-device Hive boxes
• No analytics, no telemetry, no third-party tracking
• No cloud sync — what's on your device stays on your device
• Uninstalling removes all data (backup with Export progress first)
