Map revision 4 against 535d170 for ruling operator-chromeless-column: the
sidebars go site-wide, the masthead aligns to one column token, the wash dims
off the home page through one intensity token, the composite branch is
deleted. Cut specs: wash-home-only, composite-delete, sidebars-gone,
column-align, plus community-hit-gap and doc-tree-flat for Soul's two
findings. Target r3 proposal: one-column and wash-home-only invariants.
