Subject: [PATCH 1/4] ui: Simplify style rules for body.plain in the composer

Setting these rules on `body.plain *` is not needed: they will cascade
quite happily on their own, with easier maintenance and readability for
humans

Also applies to rules whose values are unchanged from those on `body` -
better to keep these DRY
