feat: mobile-first redesign and layout improvements

## Major Changes

### Mobile-First Responsive Design
- Converted entire app to mobile-first single-column layout
- Constrained max-width to 448px (mobile phone width)
- Black margins on desktop, centered content
- Removed all multi-column grids (md:grid-cols-3)

### Header Reorganization (3-Row Layout)
- Row 1: App logo + title + version
- Row 2: Security badges + action buttons (Empty, Reset)
- Row 3: Navigation tabs (Create, Backup, Restore, Blender)
- Replaced text buttons with emoji icons (📋 clipboard, 🙈 privacy mask)
- Consistent button sizing across all tabs

### Font Size Reductions
- Reduced all button text sizes for mobile density
- Main buttons: py-4 → py-3, added text-sm
- Labels: text-xs → text-[10px]
- Placeholders: consistent text-[10px] across all inputs
- Input fields: text-sm → text-xs, p-4 → p-3

### Create Tab Improvements
- Changed "GENERATE NEW SEED" from button-style to banner
- Left-aligned banner with gradient background
- Equal-width button grid (12/24 Words, Backup/Seed Blender)
- Used grid-cols-2 for consistent sizing

### Backup Tab Improvements
- Simplified drag-drop area with 📎 emoji
- Reduced padding and text sizes
- Cleaner, shorter copy
- PGP label font size: text-xs → text-[12px]

### SeedBlender Component
- Reorganized mnemonic input cards: textarea on row 1, buttons on row 2
- QR button (left) and X button (right) alignment
- Consistent placeholder text sizing (text-[10px])
- Shortened dice roll placeholder text

### HTTPS Development Server
- Added @vitejs/plugin-basic-ssl for HTTPS in dev mode
- Configured server to listen on 0.0.0.0:5173
- Fixed Web Crypto API issues on mobile (requires secure context)
- Enables testing on iPhone via local network

-# Development Guide - SeedPGP v1.4.4
-
-## Architecture Quick Reference
-
-### Core Types
-
-```typescript
-// src/lib/types.ts
-interface SeedPgpPlaintext {
-  v: number;              // Version (always 1)
-  t: string;              // Type ("bip39")
-  w: string;              // Mnemonic words (normalized)
-  l: string;              // Language ("en")
-  pp: number;             // BIP39 passphrase used? (0 or 1)
-  fpr?: string[];         // Optional recipient fingerprints
-}
-
-interface ParsedSeedPgpFrame {
-  kind: "single";         // Frame type
-  crc16: string;          // 4-digit hex checksum
-  b45: string;            // Base45 payload
-}
-```
-
-### Frame Format
-
-```
-SEEDPGP1:0:ABCD:BASE45DATA
-
-SEEDPGP1 - Protocol identifier + version
-0        - Frame number (single frame)
-ABCD     - CRC16-CCITT-FALSE checksum (4 hex digits)
-BASE45   - Base45-encoded PGP binary message
-```
-
-### Key Functions
-
-#### Encryption Flow
-```typescript
-buildPlaintext(mnemonic, bip39PassphraseUsed, recipientFingerprints?)
-  → SeedPgpPlaintext
-
-encryptToSeedPgp({ plaintext, publicKeyArmored?, messagePassword? })
-  → { framed: string, pgpBytes: Uint8Array, recipientFingerprint?: string }
-```
-
-#### Decryption Flow
-```typescript
-decryptSeedPgp({ frameText, privateKeyArmored?, privateKeyPassphrase?, messagePassword? })
-  → SeedPgpPlaintext
-
-frameDecodeToPgpBytes(frameText)
-  → Uint8Array (with CRC16 validation)
-```
-
-#### Encoding/Decoding
-```typescript
-frameEncode(pgpBinary: Uint8Array) → "SEEDPGP1:0:CRC16:BASE45"
-frameParse(text: string) → ParsedSeedPgpFrame
-frameDecodeToPgpBytes(frameText: string) → Uint8Array
-```
-
-### Dependencies
-
-```json
-{
-  "openpgp": "^6.3.0",      // PGP encryption (curve25519Legacy)
-  "bun-types": "latest",    // Bun runtime types
-  "react": "^18.x",         // UI framework
-  "vite": "^5.x"            // Build tool
-}
-```
-
-### OpenPGP.js v6 Quirks
-
-⚠️ **Important compatibility notes:**
-
-1. **Empty password array bug**: Never pass `passwords: []` to `decrypt()`. Only include if non-empty:
-   ```typescript
-   if (msgPw) {
-     decryptOptions.passwords = [msgPw];
-   }
-   ```
-
-2. **Curve naming**: Use `curve25519Legacy` (not `curve25519`) in `generateKey()`
-
-3. **Key validation**: Always call `getEncryptionKey()` to verify public key has usable subkeys

-```
-
-### Adding Features
-
-1. **Write tests first** in `seedpgp.test.ts`
-2. **Implement in** `src/lib/seedpgp.ts`
-3. **Update types** in `types.ts` if needed
-4. **Run full test suite**: `bun test`
-5. **Commit with conventional commits**: `feat: add QR generation`
-
-## Feature Agenda
-
-### 🚧 v1.2.0 - QR Code Round-Trip
-
-**Goal**: Read back QR code and decrypt with user-provided credentials
-
-**Tasks**:
-- [ ] Add QR code generation from `encrypted.framed`
-  - Library: `qrcode` or `qr-code-styling`
-  - Input: SEEDPGP1 frame string
-  - Output: QR code image/canvas/SVG
-  
-- [ ] Add QR code scanner UI
-  - Library: `html5-qrcode` or `jsqr`
-  - Camera/file upload input
-  - Parse scanned text → `frameText`
-  
-- [ ] Build decrypt UI form
-  - Input fields:
-    - Scanned QR text (auto-filled)
-    - Private key (file upload or paste)
-    - Key passphrase (password input)
-    - OR message password (alternative)
-  - Call `decryptSeedPgp()`
-  - Display recovered mnemonic + metadata
-  
-- [ ] Add visual feedback
-  - CRC16 validation status
-  - Key fingerprint match indicator
-  - Decryption success/error states
-
-**API Usage**:
-```typescript
-// Generate QR
-import QRCode from 'qrcode';
-const { framed } = await encryptToSeedPgp({ ... });
-const qrDataUrl = await QRCode.toDataURL(framed);
-
-// Scan and decrypt
-const scannedText = "SEEDPGP1:0:ABCD:..."; // from scanner
-const decrypted = await decryptSeedPgp({
-  frameText: scannedText,
-  privateKeyArmored: userKey,
-  privateKeyPassphrase: userPassword,
-});
-console.log(decrypted.w); // Recovered mnemonic
-```
-
-**Security Notes**:
-- Never log decrypted mnemonics in production
-- Clear sensitive data from memory after use
-- Validate CRC16 before attempting decrypt
-- Show key fingerprint for user verification
-
----
-
-### 🔮 Future Ideas (v1.3+)
-
-- [ ] Multi-frame support (for larger payloads)
-- [ ] Password-only (SKESK) encryption flow
-- [ ] Shamir Secret Sharing integration
-- [ ] Hardware wallet key generation
-- [ ] Mobile companion app (React Native)
-- [ ] Printable paper backup templates
-- [ ] Encrypted cloud backup with PBKDF2
-- [ ] BIP85 child mnemonic derivation
-
-## Debugging Tips
-
-### Enable verbose PGP logging
-
-Uncomment in `seedpgp.ts`:
-```typescript
-console.log("Raw PGP hex:", Array.from(pgpBytes).map(...));
-console.log("SeedPGP: message packets:", ...);
-console.log("SeedPGP: encryption key IDs:", ...);
-```
-
-### Test with known vectors
-
-Use Trezor vectors from test file:
-```bash
-bun test "Trezor"  # Run only Trezor tests
-```
-
-### Validate frame manually
-
-```typescript
-import { frameParse } from "./lib/seedpgp";
-const parsed = frameParse("SEEDPGP1:0:ABCD:...");
-console.log(parsed); // Check structure
-```
-
-## Code Style
-
-- **Functions**: Async by default, explicit return types
-- **Errors**: Throw descriptive Error objects with context
-- **Naming**: `camelCase` for functions, `PascalCase` for types
-- **Comments**: Only for non-obvious crypto/encoding logic
-- **Testing**: One test per edge case, descriptive names
-
-## Git Workflow
-
-```bash
-# Feature branch
-git checkout -b feat/qr-generation
-
-# Conventional commits
-git commit -m "feat(qr): add QR code generation"

+ *
+ * @summary
+ * A direct and 100% logic-compliant port of the 'dice_mix_interactive.py'
+ * Python script to TypeScript for use in browser environments. This module
+ * implements XOR-based seed blending and HKDF-SHA256 enhancement with dice
+ * rolls using the Web Crypto API.
+ *
+ * @description
+ * The process involves two stages:
+ * 1.  **Mnemonic Blending**: Multiple BIP39 mnemonics are converted to their
+ *     raw entropy and commutatively blended using a bitwise XOR operation.
+ * 2.  **Dice Mixing**: The blended entropy is combined with entropy from a
+ *     long string of physical dice rolls. The result is processed through
+ *     HKDF-SHA256 to produce a final, cryptographically-strong mnemonic.
+ *
+ * This implementation strictly follows the Python script's logic, including
+ * checksum validation, bitwise operations, and cryptographic constructions,
+ * to ensure verifiable, deterministic outputs that match the reference script.
