[Feature Request]: Dedicated Zen Account for cross-platform synchronization

[SandwichEater577]

Description

Is your feature request related to a problem? Please describe.
Zen currently relies on the default Firefox Sync infrastructure. While this works for standard data (bookmarks/passwords), it fails to sync Zen's unique value propositions. Users currently lose their Workspace structures, Sidebar configurations, and Zen Mods when moving between a PC and a Laptop.

Describe the solution you'd like
I propose the development of a native Zen Account (or an enhancement to the existing sync layer) that treats the browser UI as a synchronized "State."

Key Enhancements:

Workspace Sync: Save and restore tab groups and named workspaces across all desktop instances.

Mod & Theme Sync: Automatically apply installed Zen Mods and CSS themes to any authorized device.

Sidebar & Layout Consistency: Sync the specific order and visibility of sidebar icons and "Glance" settings.

Mobile Bridge: Prepare a foundation for a future Zen Mobile app to inherit the desktop's "Zen-specific" environment.

Technical Context (src)

Component: component: sync

Platform: Cross-platform (Windows/macOS/Linux)

Reference: Currently, Firefox Sync only recognizes standard Gecko-engine data. Zen-specific data (stored in zen-themes.json and local profile prefs) is ignored during standard sync cycles.

Describe alternatives you've considered

Manual Migration: Copying profile folders manually (inconsistent and prone to corruption).

External Scripts: Using community-made backup/sync scripts, which are not user-friendly for the average person.

Additional context
As Zen moves out of Beta/Twilight, a unified account system is the "missing link" that will allow it to compete with browsers like Arc or Chrome, providing a seamless "it just works" experience across all a user's hardware.
