/* styles.css - Minimal styling for Dex Synapse View

This stylesheet contains only the necessary CSS rules to support the
Dex Synapse view and basic UI elements. It uses a dark theme,
positions a starfield canvas behind all content, and defines the
layout for the header, tab navigation, login/profile forms, suggestion
panel, and the synapse canvas.
