Theme Block for a Horizon Theme

/theme-block  Describes a theme block you want on a Horizon-based theme and has Sidekick generate it, with settings, for you to place in the editor.

Add to Sidekick

Add opens your Shopify admin with the skill prefilled; review it there and click Add. If nothing appears, use Copy and follow the steps below.

Personalize before you add

Values come from your store profile when set. Leave a field blank to keep the placeholder and fill it in Sidekick.

The skill

Suggested shortcut: /theme-block
Create a theme block: [BLOCK DESCRIPTION].

## Steps
1. Check which theme is live and whether it is built on Horizon. If it is not, stop and tell me the block feature needs a Horizon-based theme; suggest the closest built-in section instead.
2. Write a short spec before generating: block name, what it displays, which parts are editable settings (text, image, link, colour), default values, and where it should be used (product page, home, collection).
3. Generate the block with those settings, matching the theme's existing fonts and spacing. Use the theme's colour scheme settings rather than hard-coded colours.
4. Tell me exactly how to add it in the theme editor: which page, Add block, the block name, and what to fill in. Do not add it to the live theme yourself.

## Output
The spec, the confirmation that the block was generated, then the placement steps.

Do not modify existing sections or the theme's Liquid files. Do not publish theme changes.
