 The palette-independent layout lives in **`blog_share_base.css`** (note under `.blog`, mime `text/css`). It is attached to the blog root with a **second `shareCss` relation that is inherited (`isInheritable`)**, alongside the per-palette theme relation. When you switch the active palette you change ONLY the theme `shareCss` target; the base relation stays untouched.

The themes now carry only the `:root` variables and the colour-specific components. For production you can serve the minified build via `tools/minify_css.py`.
