basically embeds a full copy of the Chromium web browser into Nageru.
-HTML inputs are available from Nageru 1.7.0 onwards, but note that they are an

build Nageru with CEF.

useful, as it contains the absolute path to the theme in current use.)

exert detailed control over the graphics using Nageru alone—you will
probably want to have the theme contact some non-Nageru backend (possibly over
WebSockets) from where it can take detailed instructions.
