 * asciitube.com: a video site's layout (masthead with one field, rail, chips, a grid of 16:9 tiles,

 * monospace face, 1 px rules, square frames, no shadows, one accent (phosphor green), every picture
 * ASCII. Dark by default; "paper" when the system is light. Video screens are always black.
 * Nothing here is YouTube's: no red, no Roboto, no pill buttons, no play-triangle mark.
