What I decorated has been printed all around;
if read in the wrong way, I burn every object down.
Some of you may see me right now, depending on your device;
and I'm created and placed by keen, observant eyes.
What am I?
I'm thin and light, you overlook;
I gave the words the shape they'd took.
Where there are texts, I am of use:
Inscriptions, books, and all the news.
