Background images over their colour, interlaced pictures, and borders in every colour

Two bugs blanked most of a national weather service's front page. Its white centre column is a background image on a blue page, but Floati painted a box's background image first and its background colour on top, so any box with both showed only the colour. And its header, logos and forecast widget are interlaced PNG files, a format that stores a picture in seven passes so it can appear gradually; Floati refused those outright and showed their alt text. Images now paint over their colour, in their own place among gradient layers, and interlaced PNGs decode pixel for pixel like the reference.

border-color takes up to four colours, one per side, like border-width does. Floati gave every side the whole list, which is not a colour, so all four sides fell back to black. A software archive's cards had hard dark edges instead of soft grey ones, and CSS triangles (a box with one coloured side and three transparent ones) drew as black squares. Each side now gets its own colour, also when the colours come from CSS variables.
