[Horizon] Block to Display Variant Options as Pills on Collection Page Product Cards

A private block implementation for Horizon theme that displays text-based variant options (size, material, etc.) as pills on collection page product cards — the standard Swatches block only handles color swatches. Add the block to product cards and all variant options appear as tags at a glance.

Features

• Add as a "Variant Options" block anywhere in the product card
• Specify option names to exclude (comma-separated) to avoid duplicating what Swatches already shows
• Products with a single "Default Title" variant are automatically hidden
• Customize pill background color, text color, border color, font size, and padding from the theme editor

Files to Add / Edit

blocks/_variant-options.liquid (new file)

blocks/_product-card.liquid (add 1 line near L44)

Add {"type": "_variant-options"} to the blocks array in blocks/_product-card.liquid schema to make the block appear in the theme editor's "Add block" menu.
