Sounds like you’re juggling a lot. Keep a core set of grid rules – a single set of columns, gutters, and breakpoints – as the backbone. Then create a sandbox component library where you can tweak spacing, timing, and animation without breaking that backbone. The trick is versioning: lock the grid in a master file, copy it for experiments, and pull the best bits back in. That way your sprints stay tidy, but you still have a playground for the bold stuff. And remember, the first draft of an experiment is never the final; keep it in the attic until it’s actually useful.
