**Low vision? See the High Contrast theme: [high-contrast/README.md](high-contrast/README.md)**

A Lost Vape Thelema Solo converted to an **Evolv DNA100C**, set up for Divine Tribe heaters (**V5 XL** and **Lightning Quest**) with true TCR, Session Mode, and a custom theme, **Gremlin**.

## Gremlin - Color Themes v2.1
The current Gremlin theme has seven looks. Pick one under **MENU → THEMES** (turn on one at a time; all off is Classic):

- **Classic:** white and gray on black
- **Retro:** 80s neon green, hot pink, and cyan
- **Synth:** synthwave pink, purple, and a sunset battery bar
- **Toxic:** acid lime and purple
- **Ice:** electric cyan, frost blue, and white
- **Desert:** sunset orange and turquoise
- **Terminal:** green CRT

Themes recolor the home and lock screens and each menu's title. Also new in v2.x: an orange FIRING box while heating, a red LOW BATTERY banner under 15%, and profile-colored accents.

## Requirements
Evolv DNA color chip (DNA75C / DNA100C / DNA250C) with **international firmware (SP55.1 INT+)** for Session Mode. Requires up/select/down buttons plus fire.

**EScribe**, Evolv's free configuration software, is what loads all of this. Download it from Evolv: <https://www.evolvapor.com/escribe>. Install it, connect the mod, and let it update to the **international edition** — pick international, not US. The US edition does not expose Session Mode, and the theme will not upload without it.

## Calibrate before you rely on it
A TCR value is a starting point, not a setting: every mod and every cup reads a little differently. Run the swab test in [the setup guide](guides/setup-gremlin-theme-profiles-calibration.md) before you trust the number on the screen, then **set your working temperature at the low end and climb**. Starting cool costs you one mild session; starting hot scorches the load and shortens cup life.

Opening your mod and soldering lithium-battery circuits is at your own risk and voids warranties. Verify polarity and continuity before powering up.
