   ABOUT, AS A LETTER

   One column of first-person prose at a reading measure. Each
   chapter's title runs into its own paragraph (a real h2, set
   inline), and its sketch hangs in the margin beside it on the
   same instant-film stock as the portrait and the drawing wall.
   The page opens on a greeting with the live portrait inside the
   sentence, and closes on a signature.

   Loaded after audit-styles.css and theme.css; the old timeline
   rules there no longer match anything on this page.
