  /* The wash, on the two FIXED layers (see cockpit.css) rather than on --lamp.
     --lamp is painted on the body, so its percentages resolve against the
     DOCUMENT: on a long page the blooms sit against a box several screens tall
     and the slice that reaches the top of the SCREEN collapses to nothing —
     measured at exactly the flat page colour on a 7,244px page. Fixed layers
     are sized to the viewport and cannot care how tall the document is.
     on a dark ground a wide field turns the whole upper page into a light
     source, so it is kept tight and high.
     reef's corner is its türkis, not its orange — the opposite of lagoon, and the
     existing wash already said so (türkis at 88%, peach off at 10%). Kept.
