+# Changelog
+
+## v0.1.1
+
+### Fixed
+
+- **Binary file corruption**: `fetch_file_content` returns `Vec<u8>` instead of using `String::from_utf8_lossy`. Preview shows "Binary file" for non-UTF-8 content. (`src/github.rs:308-312`, `src/app/mod.rs:328-342`)
+
+- **Silent keyring deletion error**: `clear_secret` now prints a warning if keyring deletion fails. (`src/secure_store.rs:145-150`)
+
+- **Misleading variable name in OAuth**: Renamed `client_secret` to `device_credential` — it held the public client_id, not a secret. (`src/oauth.rs:93`)
+
+- **Terminal state recovery on OAuth**: Added `TerminalGuard` with `Drop` to restore raw mode and alternate screen if OAuth panics. (`src/app/mod.rs:30-37, 688-690`)
+
+- **Fragile test path inclusions**: Replaced `#[path = "../src/..."]` with a `src/lib.rs`. Tests now use `gitnapse::*` imports. (`src/lib.rs`, `tests/*.rs`)
+
+- **Cache hash overhead**: Replaced SHA-256 with `DefaultHasher` for cache keys. (`src/cache.rs:63-70`)
+
+- **Redundant String allocation in @me filter**: Replaced `format!`-based `haystack` with direct `Iterator::any` checks per field. (`src/github.rs:122-131`)
+
+- **Frame-by-frame String allocation in tree indent**: Precomputed `INDENTS` array replaces `"  ".repeat(n)` on every frame. (`src/app/render.rs:279`)
+
+- **Unnecessary clones**: Reduced `.clone()` calls in `load_tree_for_current_branch` and `preview_selected_file`. (`src/app/mod.rs:275-360`)
+
+- **Non-idempotent rustls provider**: `ensure_rustls_crypto_provider` now handles the `install_default` error instead of silently discarding it. (`src/oauth.rs:43-47`)
+
+- **rsplit_once clarity**: Replaced `rsplit('/').next()` with `rsplit_once('/')` in tree parsing. (`src/github.rs:247-248`)
+
+- **is_some_and idioms**: Replaced `.ok().filter().is_some()` with `.is_ok_and()` in `auth.rs` and `secure_store.rs`. (`src/auth.rs:84-95`, `src/secure_store.rs:14-17`)
+
+- **TUI event poll rate**: Reduced from 120ms to 16ms for smoother responsiveness (~60 FPS). (`src/app/mod.rs:1069`)
+
+- **Preview scroll viewport**: Replaced hardcoded 30-line viewport with the actual preview pane height from the render layout. (`src/app/mod.rs:882`)
+
+- **PageUp/PageDown step size**: Now uses half the preview viewport instead of a fixed 20 lines. (`src/app/mod.rs:897-904`)
+
+- **Terminal panic recovery**: Installed a panic hook that restores raw mode and leaves the alternate screen, preventing a stuck terminal. (`src/app/mod.rs:1049-1054`)
+
+- **Resize event handling**: Added explicit `Event::Resize` handler that updates the status bar. (`src/app/mod.rs:1090-1092`)
+
+- **Rate limit tracking**: GitHubClient now extracts `x-ratelimit-remaining` and `x-ratelimit-reset` headers from every response and exposes them via public methods. (`src/github.rs:108-131`)
+
+- **Branch pagination**: `fetch_branches` now loops over multiple pages, supporting repos with more than 100 branches. (`src/github.rs`)
+
+- **Blob API fallback**: When the Contents API returns 403 (file >1MB), automatically falls back to the Git Blobs API via SHA lookup. (`src/github.rs`)
+
+- **@me query edge cases**: Improved `parse_me_query` to handle multiple spaces after `@me`, bare `me:`, and reject `@me,` comma forms correctly. (`src/github.rs:46-93`)
+
+- **OAuth runtime reuse**: Created a shared `OnceLock<Runtime>` to avoid allocating a new tokio runtime on every OAuth login. (`src/oauth.rs`)
+
+- **Unused http dependency**: Replaced `use http::header::ACCEPT` with `use reqwest::header::ACCEPT` and removed `http = "1.3"` from Cargo.toml. (`src/oauth.rs:5`, `Cargo.toml`)
+
+- **Unused sha2 dependency**: Removed `sha2 = "0.11"` from Cargo.toml. (`Cargo.toml`)
+
+### Added
+
+- **Unit tests for syntax.rs**: 9 tests covering keyword highlighting, string/number/comment detection, max_lines, empty content, and unknown extensions. (`src/syntax.rs:134-215`)
+
+- **Unit tests for config.rs**: 3 tests for roundtrip serialization, invalid JSON handling, and missing fields. (`src/config.rs:58-83`)
+
+- **Unit tests for github.rs parse_me_query**: 11 tests covering exact match, case insensitivity, multiple spaces, language filters, comma rejection, special characters, and `me:` prefix forms. (`src/github.rs`)
+
+- **Theme externalization**: Color palette can now be customized via `theme.jsonc` in the config directory. Falls back to the built-in 16-color palette if the file is absent. (`src/config.rs:75-130`, `src/app/theme.rs:27-33`, `docs/THEME_CONFIG.md`)
+
+- **12 built-in theme presets**: X, Madrid, Lahabana, Miami, Paris, Tokio, Oslo, Helsinki, Berlin, London, Praha, Bogota. Auto-installed from `themes/` directory on first run. (`themes/*.jsonc`)
+
+- **Keybindings config**: Keybindings can be customized via `keybindings.jsonc` in config directory. Default bindings match the existing hardcoded keys. (`src/config.rs`)
+
+- **Command palette**: Press Ctrl+P to open a VS Code-style command palette with fuzzy search over available actions: search repos, switch branch, find file, clone, download, list issues/PRs, view commits/CI status, compare branches, toggle tree view, and more. Non-blocking with `std::thread::spawn` for network calls. (`src/app/mod.rs`, `src/app/render.rs`)
+
+- **Channel-based async**: Network operations run on background threads via `mpsc` channel, keeping the TUI responsive during API calls. (`src/app/mod.rs`)
+
+- **GitHub API coverage**: Added models and client methods for commits, diffs, issues, pull requests, CI check runs, starred repos, and repository lookup. (`src/models.rs`, `src/github.rs`)
+
+- **Typed error handling**: Introduced `thiserror`-based error enums (`GitHubError`, `AuthError`, `CacheError`, `OAuthError`) across all library modules, replacing raw `anyhow` strings. (`src/error.rs`, `src/github.rs`, `src/cache.rs`, `src/auth.rs`, `src/secure_store.rs`)
+
+- **Retry logic**: Network calls retry up to 3 times with exponential backoff on transient errors. (`src/github.rs`)
+
+- **Async HTTP**: GitHubClient migrated from `reqwest::blocking` to `reqwest::async` with a shared `current_thread` tokio runtime. Public API remains synchronous via `block_on`. (`src/github.rs`, `src/oauth_session.rs`, `Cargo.toml`)
+
+- **Token zeroize**: Token input buffer uses `secrecy::SecretString` and `Zeroize` on escape/save to clear sensitive data from memory. (`src/app/mod.rs`, `src/app/render.rs`)
+
+- **OAuth client_id warning**: Warning printed to stderr if no OAuth client ID environment variable is found. (`src/app/mod.rs:151-159`)
+
+- **10 TUI event tests**: Added tests for key navigation (q, /, Esc, Tab, Up/Down), token input (Esc zeroize, Enter save), and search input. (`src/app/mod.rs`)
+
+- **Preview cache binary support**: Cache now stores raw `Vec<u8>` instead of `String`, supporting binary files and ETag metadata. (`src/cache.rs:12-13, 43-88`)
+
+- **Loading indicators**: Status bar now shows "Loading..." before network operations (search, branch fetch, tree load, file preview). (`src/app/mod.rs:213, 254, 290, 355`)
+
+- **Dynamic tree indent**: Replaced the fixed 9-element `INDENTS` constant with `"  ".repeat(depth.min(20))` for arbitrary-depth directories. (`src/app/render.rs`)
+
+- **CI workflow**: Added `.github/workflows/ci.yml` that runs `cargo fmt --check`, `cargo clippy`, and `cargo test` on every push and PR. (`./github/workflows/ci.yml`)
+
+- **Docstrings**: Added documentation comments (`///`) to all public functions in `config.rs`, `cache.rs`, `syntax.rs`, and `secure_store.rs`.
+
+- **Pull request management**: View PR detail (title, body, stats, branches), approve, request changes, comment, merge, close. Browse reviews, comments, and commits per PR. Enter PR number from tree search. 8 new GitHub API methods. (`src/app/`, `src/github/`, `src/models/`)
+
+- **Custom review comments**: Approve, request changes, and comment actions prompt for custom text before submitting. Esc cancels, Enter submits. (`src/app/commands.rs`)
+
+- **PR creation**: 4-step guided wizard (title, head branch, base branch, optional body) via `Create Pull Request` in command palette. (`src/app/commands.rs`)
+
+- **Three merge methods**: Merge commit, squash, or rebase selectable from PR detail view. (`src/app/commands.rs`)
+
+- **Module refactoring**: Major codebase restructure. `src/github.rs` split into `github/` (6 files), `src/app/mod.rs` split into `app/input/` (4 files), `app/network.rs`, `app/commands.rs`, `app/actions.rs`. `src/config.rs` split into `config/` (4 files). `src/models.rs` split into `models/` (4 files). (`src/github/`, `src/app/`, `src/config/`, `src/models/`)
+
+- **DRY HTTP helpers**: `send_and_check_json()` eliminates ~200 lines of boilerplate across 12 API methods. (`src/github/mod.rs`)
+
+- **Test consolidation**: Moved 3 integration tests into `github/mod.rs`, deleted `tests/github_search_tests.rs`. (`src/github/mod.rs`)
+
+- **Dependency updates**: `keyring` 3.6 -> 4.0 + `keyring-core` 1.0, `octocrab` 0.49 -> 0.53, added `nucleo-matcher` for fuzzy search. (`Cargo.toml`)

+<p>
+  GitNapse is a Terminal User Interface (TUI) application for browsing, exploring, and managing
+  GitHub repositories directly from your terminal. It is written in Rust and uses
+  <code>ratatui</code> for rendering and <code>crossterm</code> for terminal interaction.
+</p>
+
+<h2 id="features" align="center">Features</h2>

+
+<h2 id="authentication" align="center">Authentication</h2>
+<p>
+  GitNapse supports multiple authentication sources with a clear precedence order:
+</p>
+<ol>
+  <li><strong>Environment variable</strong> <code>GITHUB_TOKEN</code></li>
+  <li><strong>OAuth session</strong> with automatic token refresh when expired</li>
+  <li><strong>Keyring</strong> via the operating system's native credential store</li>
+  <li><strong>File fallback</strong> in the config directory with restricted permissions (0600)</li>
+</ol>
+<p>
+  OAuth login uses GitHub's device flow via <code>octocrab</code>. It opens your browser,
+  displays a device code, and stores the resulting access token securely. Refresh tokens
+  are supported for extended sessions.
+</p>
+
+<h2 id="theming" align="center">Theming</h2>
+<p>
+  GitNapse ships with 12 built-in color themes: X, Madrid, Lahabana, Miami, Paris, Tokio,
+  Oslo, Helsinki, Berlin, London, Praha, and Bogota. Themes define a 16-color palette used
+  for selection highlighting. Each theme is verified for WCAG contrast compliance.
+</p>
+<p>
+  Switch themes from the command palette. Your selection is persisted and restored on next
+  launch. Custom themes can be added as <code>.jsonc</code> files in the config directory's
+  <code>themes/</code> folder. See <a href="THEME_CONFIG.md">THEME_CONFIG.md</a> for the format.
+</p>
+
+<h2 id="configuration" align="center">Configuration</h2>
+<p>GitNapse stores configuration in a platform-appropriate config directory:</p>
+<ul>
+  <li>Linux: <code>~/.config/GitNapse/</code></li>
+  <li>macOS: <code>~/Library/Application Support/com.GitNapse.GitNapse/</code></li>
+  <li>Windows: <code>C:\Users\&lt;user&gt;\AppData\Roaming\GitNapse\GitNapse\config\</code></li>

+
+<h2 id="architecture" align="center">Architecture</h2>
+<p>
+  The codebase is organized into modular directories:
+</p>
+<ul>
+  <li><code>src/app/</code> -- TUI application (state, input handling, rendering, commands, network event processing)</li>
+  <li><code>src/github/</code> -- GitHub REST API client with typed error handling and retry logic</li>

+  <li><code>src/secure_store.rs</code> -- Keyring and file-based secret storage</li>
+  <li><code>src/cache.rs</code> -- Preview cache with TTL and ETag support</li>
+  <li><code>src/syntax.rs</code> -- Syntax highlighting engine</li>
+  <li><code>src/error.rs</code> -- Typed error enums via <code>thiserror</code></li>
+</ul>
+<p>
+  Network operations run on background threads via <code>mpsc</code> channels, keeping the
+  TUI responsive during API calls. The GitHub client uses <code>reqwest</code> (async) with
+  a shared tokio runtime and automatic retry on transient errors.

+# Theme Configuration
+
+GitNapse supports custom color theming through an optional `theme.jsonc` file placed in the configuration directory.
+
+## Location
+
+The configuration directory is platform-dependent:
+
+| Platform | Path |
+|---|---|
+| Linux | `~/.config/GitNapse/` |
+| macOS | `~/Library/Application Support/com.GitNapse.GitNapse/` |
+| Windows | `C:\Users\<user>\AppData\Roaming\GitNapse\GitNapse\config\` |
+
+Place the file at `theme.jsonc` inside that directory. If the file does not exist, GitNapse uses the built-in default palette (16 colors based on a modified Dracula-inspired scheme).
+
+## Format
+
+The file uses JSON with support for `//` line comments (JSONC format).
+
+```jsonc
+{
+    // GitNapse Theme Configuration
+    "palette": [
+        [0x36, 0x35, 0x37],   // index 0  - dark background
+        [0xfc, 0x61, 0x8d],   // index 1  - pink
+        [0x7b, 0xd8, 0x8f],   // index 2  - green
+        [0xfc, 0xe5, 0x66],   // index 3  - yellow
+        [0xfd, 0x93, 0x53],   // index 4  - orange
+        [0x94, 0x8a, 0xe3],   // index 5  - purple
+        [0x5a, 0xd4, 0xe6],   // index 6  - cyan
+        [0xf7, 0xf1, 0xff],   // index 7  - light text
+        [0x69, 0x67, 0x6c],   // index 8  - dim text
+        [0xfc, 0x61, 0x8d],   // index 9  - pink (bright)
+        [0x7b, 0xd8, 0x8f],   // index 10 - green (bright)
+        [0xfc, 0xe5, 0x66],   // index 11 - yellow (bright)
+        [0xfd, 0x93, 0x53],   // index 12 - orange (bright)
+        [0x94, 0x8a, 0xe3],   // index 13 - purple (bright)
+        [0x5a, 0xd4, 0xe6],   // index 14 - cyan (bright)
+        [0xf7, 0xf1, 0xff]    // index 15 - white
+    ]
+}
+```
+
+## Palette
+
+The `palette` field is an array of RGB color tuples `[r, g, b]`. Each value is a hexadecimal byte (0x00-0xFF). Colors are indexed modulo the palette length, so you can provide any number of colors.
+
+Indexes are used cyclically for selection highlighting in the UI. For example, the first item in a list uses index 0, the second uses index 1, and so on.
+
+## Text Contrast
+
+For each palette color, GitNapse automatically selects either black or white foreground text based on the luminance of the background color. Colors with luminance >= 0.58 get black text; darker colors get white text. This ensures readability regardless of the palette values.
+
+## Customization Example
+
+To create a minimal theme with just two accent colors:
+
+```jsonc
+{
+    "palette": [
+        [0x1e, 0x1e, 0x2e],
+        [0xf3, 0x8f, 0xf8]
+    ]
+}
+```
+
+This would cycle between a dark blue-grey and a soft pink for all selection highlights.
+
+## No Palette File
+
+If `theme.jsonc` is absent or contains invalid JSON, GitNapse silently falls back to the default palette. No error is shown to the user.

+<h2 id="multi-select" align="center">Multi-Select Repositories</h2>
+<p>
+  In the repository list, press <code>Space</code> to toggle selection of the current repo.
+  Selected repos are marked with <code>*</code>. The active selection shows <code>&gt;*</code>
+  and inactive selected ones show <code>*</code>. There is no batch action implemented yet;

+<h2 id="fuzzy-file-search" align="center">Fuzzy File Search</h2>
+<p>
+  Press <code>f</code> in the repository tree view or select <code>Find File</code> from the
+  command palette. The tree file search uses the <code>nucleo-matcher</code> library for
+  fuzzy matching. Enter a search term and press <code>Enter</code> to jump to the best
+  matching file. Results are ranked by relevance score. Press <code>Esc</code> to cancel.

+
+<h2 id="themes" align="center">Theme System</h2>
+<p>
+  GitNapse ships with 12 built-in color themes: X, Madrid, Lahabana, Miami, Paris, Tokio,
+  Oslo, Helsinki, Berlin, London, Praha, and Bogota. Themes define a 16-color palette
+  used for selection highlighting across the UI.
+</p>
+<p>
+  To change the theme, use <code>Ctrl+P</code> &gt; <code>Change Theme</code> and select
+  from the list. Your choice is persisted to <code>account.json</code> and restored on
+  next launch.
+</p>
+<p>
+  Custom themes can be added by placing a <code>.jsonc</code> file in the config directory's
+  <code>themes/</code> folder. See <a href="THEME_CONFIG.md">THEME_CONFIG.md</a> for the
+  file format.
+</p>
+
+<h2 id="keybindings-config" align="center">Keybindings Configuration</h2>
+<p>
+  Keybindings can be customized by creating a <code>keybindings.jsonc</code> file in the
+  GitNapse config directory. The file uses JSONC format (supports <code>//</code> comments).
+  If the file does not exist, the built-in defaults are used.
+</p>
+<p>Example <code>keybindings.jsonc</code>:</p>
