- Add font configuration: fontsize=16, fontfamily=Arial
- Update index page with URL parameters documentation
- Improve display URLs in room generation
**Local Web Server:**

- Respect settings from GUI configuration
- Apply changes immediately without restart
**Architecture:**
- Remove PHP server implementation (Node.js recommended)
- Update all documentation to reference Node.js server
- Update default config URLs to Node.js endpoints
- Clean up 1700+ lines of PHP code

Created apache-sse-config.conf with required Apache settings to support
long-running SSE connections. Apache's mod_proxy_fcgi has a default
timeout of 30-60 seconds which kills SSE connections prematurely.
The configuration sets ProxyTimeout to 21600 seconds (6 hours) to match
HAProxy's timeout and allow long streaming sessions.
Added note to .htaccess explaining this requirement, as ProxyTimeout
cannot be set in .htaccess and must be configured in the virtual host.
To fix 504 Gateway Timeout errors:
1. Add ProxyTimeout directive to Apache virtual host config
2. Reload Apache
3. Test SSE connection

The server was calling exit() immediately when a room didn't exist,
which caused the SSE connection to open and then close right away.
This triggered EventSource to reconnect in a loop.
Now the server keeps the connection open and sends keepalives even
for rooms that don't exist yet. This is the correct SSE behavior -
maintain the connection and stream data when it becomes available.
Fixes the "connection established then immediately errors" issue
seen in diagnostic tests.

Enhanced JavaScript debugging with:
- Detailed connection state logging (CONNECTING/OPEN/CLOSED)
- EventSource object inspection
- Real-time readyState monitoring
- Verbose error information (type, target, readyState)
- URL and location details for troubleshooting
- Console grouping for organized output
This will help diagnose SSE connection issues by providing
detailed information in the browser console.

The comment said keepalives were sent every 15 seconds, but the code
uses sleep(1), so they're actually sent every 1 second. This is correct
for SSE connections - frequent keepalives prevent proxy timeouts.

Changes to .htaccess:
- Removed php_flag and php_value directives (don't work with php-fpm)
- Simplified DirectoryMatch to FilesMatch for .json files
- Added note about configuring PHP settings in php.ini/pool config
- More compatible with user directories
Added diagnostic.php:
- Tests PHP version, extensions, and configuration
- Checks storage directory permissions
- Tests Server-Sent Events (SSE) connection
- Shows server API type (php-fpm vs mod_php)
- Provides troubleshooting hints for common issues
- Live SSE connection test with detailed logging
Added data/index.php:
- Blocks direct access to data directory
- Returns 403 Forbidden
Fixes:
- php-fpm environments not respecting .htaccess PHP settings
- DirectoryMatch issues in user directories
- Hard to diagnose connection problems
Usage: Navigate to diagnostic.php to troubleshoot server issues
Created a beautiful landing page with random room/passphrase generation
and updated security model for read-only access.
New Files:
- server/php/index.html: Landing page with URL generator
Features:
- Random room name generation (e.g., "swift-phoenix-1234")
- Random passphrase generation (16 chars, URL-safe)
- Copy-to-clipboard functionality
- Responsive design with gradient header
- Step-by-step usage instructions
- FAQ section
Security Model Changes:
- WRITE (send transcriptions): Requires room + passphrase
- READ (view display): Only requires room name
Updated Files:
- server.php:
* handleStream(): Passphrase optional (read-only)
* handleList(): Passphrase optional (read-only)
* Added roomExists() helper function
- display.php:
* Removed passphrase from URL parameters
* Removed passphrase from SSE connection
* Removed passphrase from list endpoint
Benefits:
- Display URL is safer (no passphrase in OBS browser source)
- Simpler setup (only room name needed for viewing)
- Better security model (write-protected, read-open)
- Anyone with room name can watch, only authorized can send
Example URLs:
- Client: server.php (with room + passphrase in app settings)
- Display: display.php?room=swift-phoenix-1234&fade=10×tamps=true

Replaced fixed 6-color palette with dynamic HSL color generation
using the golden ratio for optimal color distribution.
Changes:
- Removed static CSS color classes (user-0 through user-5)
- Added getUserColor() function using golden ratio
- Colors generated as HSL(hue, 85%, 65%)
- Each user gets a unique, visually distinct color
- Supports unlimited users (20+)
How it works:
- Golden ratio (φ ≈ 0.618) distributes hues evenly across color wheel
- User 1: hue 0°
- User 2: hue 222° (0.618 * 360)
- User 3: hue 85° ((0.618 * 2 * 360) % 360)
- etc.
Benefits:
- No color repetition for any number of users
- Maximum visual distinction between consecutive users
- Consistent brightness/saturation for readability
- Colors are vibrant and stand out on dark backgrounds

- URL: Server endpoint (e.g., http://example.com/transcription/server.php)
- Room: Unique room name for your group
- Passphrase: Shared secret for authentication
OBS Integration:
Display URL format:
http://example.com/transcription/display.php?room=ROOM&passphrase=PASS&fade=10×tamps=true
