+# Go TUI Framework
+
+## Overview
+
+This document describes the TUI source tree represented by the project-root placeholder `source`. The structure separates shared data resources, framework-owned foundations, software-specific extensions, runtime composition, and project-level files.
+
+## Architecture
+
+### Data
+
+The `data` directory provides the common resource system for framework-owned and software-owned embedded data, using a central cabinet, data-specific ledgers, and resource handlers to register and resolve resources through a controlled and lightweight access path.

+|--------------------------------------------------------------------------
+| Description
+|--------------------------------------------------------------------------
+|
+| Name:
+|   - Cipher
+|
+| Purpose:
+|   - Provide reusable AES-256 encryption and decryption for file content.
+|   - Support standard and salted encryption formats through a unified interface.
+|
+|--------------------------------------------------------------------------
+*/
+
+/*
+|--------------------------------------------------------------------------
+| Instruction
+|--------------------------------------------------------------------------
+|
+| Guideline:
+|   - Use encrypt-standard to encrypt file content using AES-256 without salt.
+|   - Use encrypt-salted to encrypt file content using AES-256 with a cryptographically secure generated salt.
+|   - Use decrypt-standard to decrypt AES-256 encrypted file content without salt metadata.
+|   - Use decrypt-salted to decrypt self-contained encrypted files with embedded signature, version, salt, and ciphertext metadata.
+|   - Supply the AES-256 compatible key, input file path, and output file path through the configuration.
+|
+| Example:
+|   - ObrimCipher("encrypt-standard", map[string]any{
+|         "key":    key,
+|         "input":  inputPath,
+|         "output": outputPath,

+|         "key":    key,
+|         "input":  inputPath,
+|         "output": outputPath,

+|--------------------------------------------------------------------------
+| Description
+|--------------------------------------------------------------------------
+|
+| Name:
+|   - Codec
+|
+| Purpose:
+|   - Provide unified encoding and decoding capabilities using Base8,
+|     Base10, Base16, Base32, Base64, and Sqids with centralized
+|     validation, operation dispatching, transformation handling,
+|     and standardized result generation.
+|
+|--------------------------------------------------------------------------
+*/
+
+/*
+|--------------------------------------------------------------------------
+| Instruction
+|--------------------------------------------------------------------------
+|
+| Guideline:
+|   - Use the utility to encode input data using the selected codec format.
+|   - Use the utility to decode input data using the selected codec format.
+|   - Configure the codec format using base8, base10, base16, base32,
+|     base64, or sqids.
+|   - Provide input data as a string or []byte.
+|   - Configure charset and salt transformations when required.
+|   - Configure lower or upper output casing when required.
+|   - Configure minimum output length for Sqids encoding.
+|   - Configure length for deterministic Sqids decoding.
+|
+| Example:
+|   - ObrimCodec("encode", map[string]any{
+|	       "format": "base64",
+|	       "data":   "hello",
+|		})
+|
+|   - ObrimCodec("decode", map[string]any{
+|	       "format": "base64",
+|	       "data":   "aGVsbG8=",
+|		})
+|
+|   - ObrimCodec("encode", map[string]any{
+|       	"format":  "sqids",
+|       	"data":    "12345",
+|       	"charset": "abcdefghijklmnopqrstuvwxyz",
+|       	"salt":    "example",
+|       	"length":  8,

+|--------------------------------------------------------------------------
+| Description
+|--------------------------------------------------------------------------
+|
+| Name:
+|   - Status
+|
+| Purpose:
+|   - Provide a framework-level CLI status utility that standardizes
+|     terminal message presentation using semantic labels and visual
+|     indicators to ensure consistent output across all softwares.
+|
+|--------------------------------------------------------------------------
+*/
+
+/*
+|--------------------------------------------------------------------------
+| Instruction
+|--------------------------------------------------------------------------
+|
+| Guideline:
+|   - Accept a semantic status category and human-readable message.
+|   - Use INFO, WARNING, SUCCESS, and ERROR as supported status labels.
+|   - Treat unsupported, empty, or invalid labels as INFO.
+|   - Emit exactly one standardized terminal message per invocation.
+|
+| Example:
+|   - ObrimStatus(
+|       "INFO",
+|       "Application started successfully.",
+|     )
+|
+|   - ObrimStatus(
+|       "WARNING",
+|       "Configuration file not found.",
+|     )
+|
+|   - ObrimStatus(
+|       "SUCCESS",
+|       "Installation completed.",
+|     )
+|
+|   - ObrimStatus(
+|       "ERROR",
+|       "Unable to connect to the server.",
+|     )
