• CID F2 (The Accent): Often used for italics or bolding. It represents emphasis, emotion, the raising of a voice. When F2 is exposed, it is a shout rendered in wireframe.
• CID F3 (The Structure): Often headers or subheaders. The organization of thought. Without its skin, F3 is just a heavy block of lines, a brutalist pillar holding up a roof that isn't there.
• CID F4 (The Ghost): Usually footnotes or captions. The small text. The afterthought. In the CID hierarchy, F4 is the whisper that refuses to be silenced, even when the software strips it of its identity.
