Drop-in Rails engine that adds a social daily Bible reading plan over 270 days: Old Testament and New Testament once, with Psalms/Proverbs alongside. Daily portions are balanced by verse count so each day takes about the same time to read. Readers check off each day's readings, leave reflections, and see one another's progress. Designed to mount cleanly into a host Rails app such as ComfortableMediaSurfer.

A Bridgetown 2.0+ plugin that pre-generates responsive AVIF and WebP image derivatives at multiple widths, exposes a picture_tag helper for <img> elements, a bg_image_block helper that emits CSS image-set() declarations for backgrounds, and an Inspector that retroactively wraps bare <img> tags with responsive <picture> markup.

A Capybara driver that runs JavaScript against an in-process JS-resident DOM — V8 via rusty_racer or QuickJS via quickjs.rb, whichever is installed. No Chrome, no Node toolchain. Forms submit through Rack::MockRequest, inline <script> + event handlers run, Hotwire / Stimulus / Turbo work, and Capybara DSL is unchanged. Sits between rack-test and full headless browsers.

Provides Stimulus/WebGPU helpers, installer wiring, and ActiveStorage previews for OpenEXR content.
