 * A simple JS-to-CSS (aka CSS-in-JS) helper.
 *
 * The `root` parameter provides a hierarchical description of CSS rules.
 *
 * - Keys of sub-objects whose values are NOT objects are treated as CSS attribute, and values are treated as values of those CSS attributes; the concatenation of keys of all parent objects is a CSS rule.
 * - 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`), while all `_` characters are replaced by `-` character (e.g. `font_family` → `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.

 * - All other arguments of type `Record<PropertyKey, unknown>` are mappings of attributes and properties.

 * - All other arguments of type `null` or `undefined` are simply ignored.
 * - All other arguments of type `Node` are appended to the element being created or modified.
 * - All other arguments of type `string`/`number` are converted to `Text` nodes and appended to the element being created or modified.
 * - All other arguments of type `HArgs` are passed to `h` and the results are appended to the element being created or modified.
