Style sheets in page order, and symbols that fall back like macOS

Three things kept a tutorial site's home page from looking like the reference. Its own style block, written after its framework's file to override it, was applied before that file, so the framework won: the hero sat inside side gutters under a white band. Its centred column, width 100% with a max-width, filled the row because a flex line decided whether to grow or shrink before applying that max-width. And its check marks, drawn by absolutely positioned decorations inside grid items, were lost on the grid's second layout pass. All three now behave as the reference does.

When a page's font lacks a symbol, Floati used the first installed font that had it, so a writing hand came from a programming font as a small outline. macOS tries its symbols font first and draws some text symbols, like the hands and figures that take skin tones, as emoji. Measured across all 214 such characters in the reference browser, Floati now picks the same font for 66 of its 67 pictures, and the rest stay text.
