Add BTClock

[dsbaars]

Proposal

Add brand assets for the BTClock custom integration.

Integration

• Repository: https://github.com/dsbaars/homeassistant-btclock
• Domain: btclock
• Hardware: https://git.btclock.dev/btclock/btclock_v3 — open-source ESP32-based Bitcoin price / block-height e-paper display

Assets

• icon.png / icon@2x.png — 256×256 / 512×512, near-black rounded tile with Bitcoin-orange "BTClock" wordmark (readable on both light and dark backgrounds)
• logo.png / logo@2x.png — black "BTClock" wordmark on transparent, for light backgrounds
• dark_logo.png / dark_logo@2x.png — Bitcoin-orange wordmark for dark backgrounds

Checklist

• PNGs only (no SVG)
• icon is a square 256×256 (+@2x 512×512)
• Logo is transparent PNG
• Dark variant provided because the default logo is near-black
• Integration already shipping via HACS

Hi there 👋🏻

Thank you for your PR! We really appreciate the contribution.

However, we'll be closing it, as we no longer accept brand icons for custom integrations in this repository. Starting with Home Assistant 2026.3.0, custom integrations can provide their own brand icons directly, so there's no longer a need to add them here.

You can find more details in the announcement:
