What

Create a logo for SIMUT — icon + wordmark — and update the favicon.

Why

SIMUT currently has no visual identity beyond emoji and a generic favicon. A logo makes the project recognizable on GitHub, in the web UI, on the TFT boot screen, and in the browser tab.

⚠️ Resource constraints (READ THIS)

The RP2040 has 2 MB total flash — 98.7% used. The favicon lives in LittleFS (data/favicon.ico), which shares that 2 MB with firmware, language packs, config, and history files. Every byte matters. Logo on the TFT boot screen must be tiny — a few hundred bytes of C array, rendered at ×ばつ240 in 16-bit RGB565.

Scope

• Logo icon (SVG, ×ばつ128 min)
• Optional wordmark variant ("SIMUT" text + icon)
• Favicon (.ico, ×ばつ32 from the icon)
• Add logo to README.md header
• Replace data/favicon.ico

Design direction

• Feeling: Professional, trustworthy, modern embedded/IoT
• Concepts: Thermometer + radio waves, chip + shield, temperature + connectivity
• Colors: Blue (#1a73e8) + amber (#ffd54f) on dark backgrounds
• Constraint: Must be recognizable at ×ばつ32 (favicon) and clean at ×ばつ128 (README)

References

• data/favicon.ico — current favicon
• src/Themes.h / src/Themes.cpp — project color palette
• TFT is ×ばつ240 — boot screen renders at this resolution

Acceptance

• Logo SVG submitted (icon + optional wordmark)
• Favicon .ico generated at ×ばつ32
• README.md updated with logo above the title
• data/favicon.ico replaced
• Logo works on both light and dark backgrounds
• Favicon stays under 2 KB (LittleFS space is tight)
