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

Phase 2 implementation: Multiple streamers can now merge their captions
into a single stream using a PHP server.
PHP Server (server/php/):
- server.php: API endpoint for sending/streaming transcriptions
- display.php: Web page for viewing merged captions in OBS
- config.php: Server configuration
- .htaccess: Security settings
- README.md: Comprehensive deployment guide
Features:
- Room-based isolation (multiple groups on same server)
- Passphrase authentication per room
- Real-time streaming via Server-Sent Events (SSE)
- Different colors for each user
- File-based storage (no database required)
- Auto-cleanup of old rooms
- Works on standard PHP hosting
Client-Side:
- client/server_sync.py: HTTP client for sending to PHP server
- Settings dialog updated with server sync options
- Config updated with server_sync section
Server Configuration:
- 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
NOTE: Main window integration pending (client sends transcriptions)
