Meridian OS — PRD

Vision

A browser-based desktop environment for a video game. Elegant, restrained, gamer-literate without being loud. No emoji stuffing, no AI-slop aesthetics.

Personas

Player who boots the in-game computer and wants to feel at home.
Easter-egg hunter who wants rewards for exploration.

Core Requirements

Login screen (any username, stored locally, avatar = initials).
Desktop with changeable wallpaper (gallery of 6 curated gradients/images).
Taskbar: start-equivalent launcher, active apps, widgets tray, status bar.
Status bar: username, time (live), connection state, date.
Widgets: date, active applications. Optional: achievements tray.
Window manager: drag, focus, minimize, close. Multi-window.
Apps:
- Notepad (text editing, localStorage persistence)
- Music player (3 tracks, play/pause/skip/seek, volume)
- Terminal (command parser, easter eggs, ANSI-ish styling)
- Spoof: Steam, VS Code, Postman, Chrome (static-but-believable UIs)
Special feature: Achievement system (game-flavored, tracks real usage).

Non-Requirements

Real authentication
Real networking
Real OS features (files beyond localStorage)

Aesthetic Direction

Palette: slate/graphite base (#0f1114, #1a1d21, #252a31), amber accent (#d4a24c).
Type: Inter (400/500/600).
Borders: 1px rgba(255,255,255,0.06–0.1).
Shadows: subtle only; never blurry-neon.
Motion: 150–220ms ease-out; no bounce, no parallax.
No emojis in chrome. Allowed sparingly in content (terminal output, toasts).

Easter Eggs (Terminal)

Elden Ring: praise_the_sun, tarnished, "try finger, but hole" CoD: dropshot, 360_noscope, mw2 FIFA: siuuu, golazo, wonderkid Misc: konami, matrix, sudo rm -rf /
