The Showcase child theme taught me another child-theme lesson: sometimes one visual direction is not enough.
The first Showcase design had energy. It was colorful, loud, graphic, and useful for breaking away from the generic SaaS look I did not want. But after living with it for a while, I wanted to keep it without being trapped by it.
I did not want to delete the old design. I also did not want every template path, helper path, component path, and CSS path hardcoded to one visual system forever.
That is where the design-pack idea entered the Showcase child theme.
A design is more than one CSS file
A real design direction has its own assets, components, page templates, CSS, JavaScript, metadata, and sometimes entity-page treatment. So the cleaner structure was to let a design pack carry all of that together.
Now the Showcase child theme can keep multiple visual systems side by side. One pack can be the fun experimental version. Another can be the more editorial/professional version. The active pack can be defined in the child theme configuration, while the parent theme stays untouched.
This is a small evolution, but it fits the larger Lubinik philosophy. Do not force a reusable layer to know about a site-specific decision. Do not throw away a working experiment just because the next iteration needs a different mood. Give each layer a place to carry the knowledge that belongs to it.
The design pack system is still a practical tool, but it is also a reminder: design evolves too, and the architecture should leave room for that.
