For DreamHost hosting, the owner of `feed.falsefinish.club` can configure CORS headers using an `.htaccess` file in the root directory of the site (or in the specific directory serving the audio files).
## Setting CORS Headers on DreamHost
Create or edit the `.htaccess` file in the web root (typically `~/falsefinish.club/feed/` or wherever the audio files are served from) and add:
```apache
# Enable CORS for echo-reality.com
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "https://echo-reality.com"
Header set Access-Control-Allow-Methods "GET, HEAD, OPTIONS"
Header set Access-Control-Expose-Headers "ETag, Last-Modified, Content-Length"
</IfModule>
# Handle preflight OPTIONS requests
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]
</IfModule>
```
### If targeting specific file types only (recommended)
To apply CORS headers only to audio files:
```apache
<IfModule mod_headers.c>
<FilesMatch "\.(mp3|mp4|wav|ogg|m4a)$">
Header set Access-Control-Allow-Origin "https://echo-reality.com"
Header set Access-Control-Allow-Methods "GET, HEAD, OPTIONS"
Header set Access-Control-Expose-Headers "ETag, Last-Modified, Content-Length"
</FilesMatch>
</IfModule>
```
### For multiple origins (if needed during development)
If you need to allow both the production domain and a local development server:
```apache
<IfModule mod_headers.c>
SetEnvIf Origin "^https://(echo-reality\.com|localhost:3000)$" CORS_ORIGIN=$0
Header set Access-Control-Allow-Origin "%{CORS_ORIGIN}e" env=CORS_ORIGIN
Header set Access-Control-Allow-Methods "GET, HEAD, OPTIONS"
Header set Access-Control-Expose-Headers "ETag, Last-Modified, Content-Length"
</IfModule>
```
### How to add the .htaccess file on DreamHost
1. **Via SFTP/FTP**: Connect to the server using an FTP client (like FileZilla) and upload/edit the `.htaccess` file in the appropriate directory
2. **Via DreamHost Panel File Manager**: Log into the DreamHost panel → Manage Websites → Files → navigate to the directory and create/edit `.htaccess`
3. **Via SSH** (if enabled): SSH into the server and use a text editor like `nano` or `vim`
### Important notes for DreamHost
- DreamHost's shared hosting uses Apache, so `.htaccess` files work out of the box
- The `mod_headers` module is enabled by default on DreamHost
- Make sure the `.htaccess` file has proper permissions (644)
- Changes take effect immediately—no server restart needed
### Testing the configuration
After adding the `.htaccess` file, the owner can verify it's working by checking the response headers:
```bash
curl -I -X OPTIONS -H "Origin: https://echo-reality.com" \
"https://feed.falsefinish.club/Echo%20Reality/PINK%20FLIGHT/MP3%20BOUNCE/01.%20PINK%20FLIGHT%20ATTENDANT.mp3"
```
The response should include the `Access-Control-Allow-Origin: https://echo-reality.com` header.
### Quick test `.htaccess` for DreamHost
```apache
# TEMPORARY - Allow all origins for testing
<IfModule mod_headers.c>
<FilesMatch "\.(mp3|mp4|wav|ogg|m4a)$">
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Methods "GET, HEAD, OPTIONS"
Header set Access-Control-Expose-Headers "ETag, Last-Modified, Content-Length"
</FilesMatch>
</IfModule>
```
This limits the wildcard CORS to just media files, which is a reasonable middle ground—your audio files are publicly accessible but you're not opening up everything on the domain.

Let me take a look at what's currently in the project to understand the existing features and theme better.
[1 tool called]
This is a really well-crafted project with a lot of nice details already. Let me put together some ideas for easter eggs and tweaks that would fit the retro dystopian/broken cassette player theme.
Based on what I see in the code, you already have:
- CRT scanlines and flicker effects
- Cracked display overlay
- Worn/faded button icons
- Damage texture overlay
- Tape wind sound effects
- Bouncing track name marquee
Here are some ideas that would complement the existing aesthetic:
---
## Visual Glitch / Distortion Effects
1. **Random screen glitches** - Occasional RGB channel separation or horizontal displacement that happens randomly or when interacting with controls (like the display is malfunctioning)
2. **Dead pixels** - A few permanently "stuck" green pixels on the CRT display
3. **Screen burn-in** - Faint ghost image of "PLAY" or old track names that lingers on the display
4. **Intermittent display failure** - Rare chance of the display going dark for a split second then flickering back on
5. **VHS tracking lines** - Occasional horizontal noise bars that scroll up the display
---
## Audio Quirks
6. **Tape flutter/wow** - Subtle pitch wobble effect using Web Audio API's `playbackRate` with slight random variations, like a worn tape mechanism
7. **Random audio dropouts** - Very brief moments where audio cuts out or gets muffled (like dirty tape heads)
8. **Static between tracks** - White noise/hiss during track transitions
9. **"Tape eating" event** - Rare chance when pressing play/stop that triggers a tape-eating sound effect and animation where the tape visually tangles
---
## Hidden Interactions
10. **Konami code** - Entering the classic code unlocks a secret mode (different color scheme, hidden track, or "repaired" mode where everything works perfectly)
11. **Thump to fix** - Double-clicking/tapping the cassette housing "thumps" the player, which could temporarily fix glitches or cause new ones
12. **Secret button combo** - Holding certain buttons together reveals hidden content or debug info
13. **Dust accumulation** - Animated dust particles that slowly build up on the display, clickable to "wipe clean"
---
## Dystopian Theme Additions
14. **Redacted track names** - Occasional text that appears with black boxes like "[REDACTED]" or "TRACK ██ - ████████"
15. **Surveillance indicator** - Small red "REC" light in the corner that occasionally blinks, or a subtle camera icon
16. **Propaganda interruptions** - Random brief messages that flash on screen like "COMPLIANCE IS FREEDOM" or "REPORT SUSPICIOUS ACTIVITY"
17. **Emergency broadcast** - Rare event where audio cuts to an emergency alert tone with scrolling text
18. **Signal interference** - Brief moments where the display shows "NO SIGNAL" or "WEAK SIGNAL"
---
## Time-Based Behaviors
19. **Midnight mode** - Different behavior or color scheme between certain hours (dimmer, more glitchy, or eerier)
20. **Battery drain simulation** - After extended use, everything gradually slows down and gets distorted until "recharged" (refreshing the page)
---
## Fun Visual Additions
21. **Tape label graffiti/stickers** - Small worn stickers or handwritten notes on the cassette
22. **Cigarette burn marks** - Subtle burn marks on the player casing
23. **Fingerprint smudges** - Subtle smudges on the tape window or display
24. **"Property of..." label** - A worn/scratched identification label with mysterious text
---
Would you like me to create a plan to implement some of these? If so, which ones appeal to you most? I can group them into:
- **Quick wins** (CSS-only or simple JS)
- **Medium effort** (Web Audio effects, animations)
- **Larger features** (Konami code, emergency broadcast system)
