feat: add comprehensive login page customization options
Add CLI arguments and environment variables to customize all login page elements: - Login title, subtitle, and welcome text - Password field placeholder and submit button text - Password instruction messages (config file, env var, hashed) - Error messages (rate limit, missing/incorrect password) New CLI options: --login-title, --login-below, --password-placeholder, --submit-text --login-password-msg, --login-env-password-msg, --login-hashed-password-msg --login-rate-limit-msg, --missing-password-msg, --incorrect-password-msg New environment variables: CS_LOGIN_TITLE, CS_LOGIN_BELOW, CS_PASSWORD_PLACEHOLDER, CS_SUBMIT_TEXT CS_LOGIN_PASSWORD_MSG, CS_LOGIN_ENV_PASSWORD_MSG, CS_LOGIN_HASHED_PASSWORD_MSG CS_LOGIN_RATE_LIMIT_MSG, CS_MISSING_PASSWORD_MSG, CS_INCORRECT_PASSWORD_MSG Features: - Full backwards compatibility with existing --app-name/--welcome-text - HTML escaping for security (prevents XSS) - Config file support (YAML) - Priority: CLI args > env vars > config file > defaults - Internationalization preserved for non-customized messages Perfect for Docker deployments and corporate branding. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

### Login page customization
85+
86+
You can customize the login page appearance using CLI flags or environment variables:
87+
88+
**CLI flags:**
89+
```bash
90+
code-server --login-title "My Code Server" \
91+
--login-env-password-msg "Password set via environment" \
92+
--password-placeholder "Enter password" \
93+
--submit-text "LOGIN"
94+
```
95+
96+
**Environment variables:**
97+
```bash
98+
export CS_LOGIN_TITLE="My Code Server"
99+
export CS_LOGIN_ENV_PASSWORD_MSG="Password set via environment"
100+
export CS_PASSWORD_PLACEHOLDER="Enter password"
101+
export CS_SUBMIT_TEXT="LOGIN"
102+
code-server
103+
```
104+
105+
**Config file:**
106+
```yaml
107+
bind-addr: 127.0.0.1:8080
108+
auth: password
109+
password: your-password
110+
login-title: "My Code Server"
111+
login-env-password-msg: "Password set via environment"
112+
password-placeholder: "Enter password"
113+
submit-text: "LOGIN"
114+
```
115+
116+
CLI flags take priority over environment variables, which take priority over config file settings.

Many shortcuts will not work by default, since they'll be "caught" by the browser.

## Docker Examples
95+
96+
### Basic Docker Deployment with Customization
97+
98+
```bash
99+
docker run -it --name code-server -p 127.0.0.1:8080:8080 \
100+
-v "$PWD:/home/coder/project" \
101+

103+
-e "CS_PASSWORD_PLACEHOLDER=Enter development password" \
104+
-e "CS_SUBMIT_TEXT=ACCESS ENVIRONMENT" \
105+
codercom/code-server:latest
106+
```
107+
108+
### Corporate Branding Example
109+
110+
```bash
111+
docker run -it --name code-server -p 127.0.0.1:8080:8080 \
112+
-v "$PWD:/home/coder/project" \
113+
-e "CS_APP_NAME=ACME Corporation Dev Portal" \

119+
codercom/code-server:latest
120+
```
121+
122+
## Priority Order
123+
124+
Settings are applied in the following priority order (highest to lowest):
125+
126+
1. **CLI arguments** - Highest priority
127+
2. **Environment variables** - Medium priority
128+
3. **Config file** - Lowest priority
129+
130+
This allows you to set defaults in your config file and override them with environment variables or CLI arguments as needed.
131+
132+
