Theme Name: Sprocket
Theme URI: https://bikematch.network/
Author: Margaret Atwood
Description: Standalone theme for bikematch.network — an Alberta/Canada online-slots mechanics desk. Structural idea: "The Cassette Strip" — a horizontal row of size-graduated circles (largest to smallest, echoing a bicycle cassette) as the category filter, above a flush single-column entry list with no left-rail glyph, no card border and no table, rows divided by a zig-zag "gear-notch" rule instead of a plain hairline.
Version: 760a3298
Requires at least: 6.0
Requires PHP: 7.4
Text Domain: sprocket
