UI v2 08 — Introduce overview/investigate density modes

[fabriziosalmi]

Objective

Introduce explicit density layering so the product supports both overview reading and deep investigation without trapping every surface in a compromised middle state.

Why

The current product needs both glanceability and depth. UI v2 should support both deliberately instead of mixing them into the same components.

Likely files touched

• ui/style.css
• ui/index.html
• ui/main.js
• ui/services/store.js
• ui/components/threats.js
• ui/components/registry.js
• ui/components/security.js
• ui/components/logs.js
• ui/components/models.js
• ui/components/analytics.js

Example implementation surface

• Define at least two explicit density modes:

DensityMode
- overview
- investigate

• Use progressive disclosure so overview stays clean while investigate mode unlocks denser tables, relation panels, timelines, and evidence blocks.
• Keep a sticky context bar so users never lose scope while moving into dense analysis.

Acceptance criteria

• Overview remains readable in seconds.
• Investigate mode supports dense workflows without forcing the same density on the landing experience.
• Transition between modes preserves scope and context.
