/* appingale.dev
   Layout: a drawing board. The page is a sheet of graph paper (a blueprint in dark mode); the hero draws one screen of
   an app at a time on it, the studio's apps are pinned up as figures with numbered captions, the process is a strip
   of the same drawings, and the footer is the sheet's title block. Archivo in three widths: wide for headings, normal
   for text, narrow for captions and labels. Colors are drafting tools: graphite ink, non-photo blue pencil and the
   amber highlighter of the logo. */
