[FEATURE] "Ghost City" Mode for Zero Contributions

[Animesh-86]

Goal

Implement a wireframe/blueprint visual mode for days with zero contributions to maintain the "monolith" structure at all times.

Description

Currently, the isometric grid renders very faint, flat shapes for days with zero contributions. This can make the monolith look "empty" or "broken" for new users or during inactive periods.

The "Ghost City" mode will ensure the grid always looks like a structured architectural landscape.

Key Requirements:

1. Blueprint Visuals: Use stroke and low-opacity fill to create a 3D wireframe/blueprint effect for empty towers.
2. Architectural Foundation: Give empty days a tiny "foundation" height (e.g., 2px) so the 3D grid remains visible.
3. Aesthetic Consistency: The "ghost" towers should blend with the current theme but look distinctly like unbuilt structures.

Pillar

• Pillar 2 — Geometric SVG Improvement

Expected Outcome

A premium, blueprint-style isometric grid that looks like a structured city plan even with zero contributions, preventing the "empty monolith" look.

Hi @JhaSourav07 👋

I'm a GSSoC '26 contributor and would love to work on this!

My approach:

• Add a minimum foundation height (2px) for zero-contribution days
• Use SVG stroke with low-opacity fill for wireframe/blueprint effect
• Keep ghost tower colors derived from the current theme accent
  so it stays visually consistent across all themes

I can submit a PR within 2-3 days.
Please assign this to me 🙏
