[tilo-14]

Summary

• Add comprehensive compressed token program documentation with cMint and cToken guides
• Add program-side guide for creating cToken accounts via CPI
• Add reusable snippets for rent comparison and account lists
• Update docs.json navigation structure for compressed token program sections

New Documentation Files

Core Overview:

• compressed-token-program/c-token-program.mdx - Main overview with cMint and cToken concepts

cMint Guides:

• compressed-token-program/cmint/cmint.mdx - Create cMint with token metadata (client/program tabs)
• compressed-token-program/cmint/update-metadata.mdx - Update cMint metadata

cToken Guides:

• compressed-token-program/ctoken/create-ctoken.mdx - Create cToken accounts from clients
• compressed-token-program/ctoken/program-create-ctoken.mdx - Create cToken accounts from programs via CPI
• compressed-token-program/ctoken/mint-ctokens.mdx - Mint cTokens
• compressed-token-program/ctoken/create-ata.mdx - Create associated token accounts
• compressed-token-program/ctoken/ctoken-transfer.mdx - Transfer cTokens
• compressed-token-program/ctoken/SPL-to-ctoken-transfer.mdx - Transfer SPL to cToken (compress)
• compressed-token-program/ctoken/ctoken-to-spl-decompress.mdx - Transfer cToken to SPL (decompress)
• compressed-token-program/ctoken/close-ctoken.mdx - Close cToken accounts
• compressed-token-program/ctoken/compress-and-close.mdx - Compress and close accounts
• compressed-token-program/ctoken/mint-actions.mdx - Mint authority actions

Reusable Snippets:

• snippets/compressible-vs-solana-rent.mdx - Rent comparison accordion
• snippets/ctoken-create-accounts-list.mdx - Account list table for CPI
• snippets/install-dependencies-codegroup.mdx - Installation instructions (referenced)

Key Features

• Program-side CPI guide with invoke() and invoke_signed() examples
• Client/program tabs for flexible implementation approaches
• Detailed rent model explanations with compressible extension
• Code examples with inline comments and full working implementations
• Structured navigation with expanded/collapsed sections in docs.json

Test Plan

• Verify all internal links resolve correctly
• Confirm code snippets render properly in both TypeScript and Rust tabs
• Test accordion components (Account List, Compressible vs Solana Rent)
• Validate navigation structure in docs.json
• Review metadata frontmatter for all new files
• Ensure reusable snippets import correctly across pages
