 * - All keys ignore the part starting with a splitter (default: `$$`) sign until the end of the key (e.g. `src$$1` → `src`, `@font-face$$1` → `@font-face`).
 * - In keys specifying CSS attribute, all uppercase letters are replaced by lowercase letters with an additional `-` character preceding them (e.g. `fontFamily` → `font-family`).
 * - Commas in keys that makes a CSS rule cause it to “split” and create separate rules for each part (e.g. `{div:{margin:1,'.a,.b,.c':{margin:2}}}` → `div{margin:1}div.a,div.b,div.c{margin:2}`).
 * - Top-level keys that begin with `@` are not concatenated with sub-object keys.
