 ## Code Style Guidelines
 
 ### General Principles
-- Use CamelCase for function and variable names (Emacs Lisp convention)
-- Prefix all public functions/variables with a project-specific namespace: `my-dashboard-`
-- Use kebab-case for keymap names: `my-dashboard-mode-map`
+- Use kebab-case for function and variable names (Emacs Lisp convention)
+- Prefix all public functions/variables with project namespace: `ppq-` or `nano-gpt-`
+- Private functions/variables: prefix with `--` (e.g., `ppq--internal`)
+- Use `lexical-binding: t` in file header
 
 ### Naming Conventions
-- Functions: `my-dashboard-function-name`
-- Variables: `my-dashboard-variable-name`
-- Private functions/variables: prefix with `--` (e.g., `my-dashboard--internal`)
-- Modes: `my-dashboard-foo-mode`
-- Keymaps: `my-dashboard-foo-mode-map`
+- Functions: `ppq-function-name` or `nano-gpt-function-name`
+- Variables: `ppq-variable-name` or `nano-gpt-variable-name`
+- Private functions/variables: `ppq--function-name` (double dash)
+- Modes: `ppq-foo-mode`
+- Keymaps: `ppq-foo-mode-map`
 - Buffer names: `*Dashboard:Name*`
+- Custom groups: `ppq` or `nano-gpt`
 
 ### Formatting
 - Indent using 2 spaces (Emacs default for Elisp)
 - Maximum line length: 80 characters
-- Use `setq` for setting variables, `defvar` for defining variables with docstrings
-- Place docstrings on the line after `defun`/`defvar` opening paren
-- Use consistent spacing around operators: `(+ x y)` not `(+x y)`
+- Use `setq` for setting variables, `defvar` for defining with docstrings
+- Place docstrings on line after `defun`/`defvar` opening paren
+- Consistent spacing around operators: `(+ x y)` not `(+x y)`
 
 ### Imports and Dependencies
-- Use `(require 'module)` at the top of files
-- Common dependencies: `url`, `json`, `tabulated-list`, `org`
-- Use `use-package` for declarative package management if needed
+- Use `(require 'module)` at top of file after header
+- Common dependencies: `url`, `json`, `auth-source`, `org`, `tabulated-list`, `hl-line`
+- Use `(declare-function func "file")` for external functions (e.g., `qrencode-string`)
 
 ### Types
 - Use `:type` property in `defcustom` for customization types
-- Use type predicates: `numberp`, `stringp`, `listp`, `functionp`, `bufferp`
+- Use type predicates: `numberp`, `stringp`, `listp`, `functionp`, `bufferp`, `vectorp`
 - Check for nil explicitly: `(when var ...)` not `(if var ...)`
 - Use `eq` for symbol comparison, `equal` for lists/strings
 
 ### Error Handling
 - Use `condition-case` for error catching
-- Check API error status with `plist-get status :error`
+- For async URL operations, check status with `(plist-get status :error)`
 - Provide meaningful error messages in docstrings
 - Handle `:null` values from JSON parsing explicitly
 
 ### Keymap Conventions
 - Use `make-sparse-keymap` for mode keymaps
-- Set keymap parent to appropriate mode map (e.g., `tabulated-list-mode-map`)
-- Define keys using `define-key` with key sequences as strings (e.g., "q", "C-x C-f")
+- Set keymap parent: `(set-keymap-parent map tabulated-list-mode-map)`
+- Define keys using `define-key` with string sequences (e.g., "q", "C-x C-f")
 - Use `setq` with `let` for local keymap creation

 - Set `tabulated-list-format` and `tabulated-list-entries`
 - Call `tabulated-list-init-header` and `tabulated-list-print`
 - Set `inhibit-read-only` before modifying read-only buffers
+- Enable `hl-line-mode` for highlighting current line
 
 ### Async Operations
 - Use `url-retrieve` for async HTTP requests
 - Define callback functions with `status` parameter
-- Check for errors with `plist-get status :error`
-- Use `goto-char (point-min)` before parsing buffer content
-- Use `re-search-forward` to skip HTTP headers in response
+- Check for errors: `(unless (plist-get status :error) ...)`
+- Use `(goto-char (point-min))` before parsing buffer content
+- Use `(re-search-forward "^$" nil t)` to skip HTTP headers
 
 ### Documentation
-- Every `defun` and `defvar` should have a docstring
+- Every `defun` and `defvar` must have a docstring
 - Docstrings start with descriptive verb ("Show", "Fetch", "Copy")
 - Document interactive commands with `(interactive)` and "Calling from program..."
+- Use `;;;###autoload` for user-facing commands
 
 ### Package Management
 - Use `defcustom` for user-configurable variables with `:type`, `:group`, `:default`
