🇭🇰 中文說明

常慶功 (Always Celebrate) 是一款結合極致零知識資安 (Zero-Knowledge Security) 與心理學「預祝法則」(Pre-Celebration Mindset) 的企業級離線日記與願望艙 PWA 應用。

本專案旨在為現代人在 AI 時代提供一個 100% 安全、純本地端、零數據上雲的個人心靈避風港與願望管理工具。

✨ 核心亮點

• 🔒 零知識資安架構 (Zero-Knowledge Architecture)：採用 AES-GCM 256-bit 端到端本地加密，金鑰透過 PBKDF2 (600,000 次疊代) 衍生。密碼與內容僅存於本機記憶體，零數據上雲。
• 🛡️ 防 AI 數據採集 (Anti-AI Scraping)：配置極嚴格的 Content Security Policy (connect-src 'none')，徹底封殺所有網絡出站連線，確保個人願望與私密日記絕不被 LLM 爬蟲採集或訓練。
• 🎯 預祝法則與心理賦能 (Pre-Celebration Engine)：依據日本「前祝いの法則」心法，引導使用者運用「已完成的肯定句」撰寫目標，透過情緒轉化調降威脅感知（Threat Perception），驅動實質執行力。
• 🧱 逆境轉化與未來信箱 (Crisis Flip & Time Capsule)：提供「逆境轉化卡」（將障礙/牆重塑為機會/門）與「未來慶功信箱」，協助個人與團隊進行心理韌性覆盤。
• 📱 PWA 離線秒開 (Offline-First Service Worker)：完整註冊 sw.js 快取，無網路環境（飛機、地鐵）下 100% 可用。
• 💾 企業級數據備援 (Encrypted Backup & Recovery)：支援一鍵匯出與還原經 AES-GCM 加密的 .alwayscelebrate 備份檔，跨裝置遷移安全無憂。
• ⌛ 閒置自動鎖定與防暴力破解 (Enterprise DLP Guard)：無操作 5 分鐘自動鎖定並清除記憶體金鑰；連續 5 次密碼錯誤自動觸發速率限制（Rate Limiting）。

   • 🧱 逆境轉化：寫下當前挑戰，並預祝這件事帶來的轉機。
   • ✉️ 未來信：設定未來日期，撰寫給達成目標後自己的慶功信。
4. 存檔與慶功：點擊 ✨ 加密預祝並慶功 (快捷鍵：Ctrl + Enter)，資料即刻完成本地加密持久化並觸發慶功特效。

🇬🇧 English Description

Always Celebrate is an enterprise-grade, zero-knowledge, offline-first Web Application combining military-grade Web Crypto API encryption with the Pre-Celebration Mindset (mental simulation for goal achievement).

Built for privacy-conscious users in the AI era, it serves as a pure local sanctuary where your personal goals, entries, and future aspirations remain completely isolated from cloud databases and AI scraping crawlers.

✨ Key Features

• 🔒 Zero-Knowledge Architecture: Powered by AES-GCM 256-bit encryption with PBKDF2 key derivation (600,000 iterations) adhering to OWASP recommendations. Keys exist exclusively in your local device RAM.
• 🛡️ Anti-AI Scraping Shield: Enforces a strict Content Security Policy (connect-src 'none'), blocking all outbound network requests. Guaranteed zero cloud leakage and zero LLM training data harvesting.
• 🎯 Pre-Celebration Engine: Harnesses cognitive mental simulation by encouraging users to frame future objectives as already achieved, reducing anxiety and fostering execution resilience.
• 🧱 Crisis Flip & Time Capsule: Structural workflows to reframe current obstacles into setup stories for future victory, alongside date-locked letters to your future self.
• 📱 PWA Offline-First: Integrated Service Worker (sw.js) guarantees 100% instant loading without internet connectivity (e.g., in flight or subway).
• 💾 Encrypted Backup & Restore: Port encrypted vault backups (.alwayscelebrate files) safely across devices without exposing plaintext data.
• ⌛ Enterprise DLP Controls: Auto-locks vault after 5 minutes of inactivity; features rate-limiting against brute-force password guessing.
