fix(player): marks are weighed when answered, lit and pressed hold under the pointer, and Restart is one glyph

The watched toggle weighed its own click at click time against marks stamped when the server answered, so the late answer of its previous click overruled the newer one; it now holds its word while any of its writes is on the way, is stamped at the answer, and drops a refused write. The hosts return the write. In a live search the feed's own answered writes stand down over the rows, which carry the marks, so a newer mark from the related list reaches a card the feed touched earlier.

A lit mode cycle got the hover layer, and a variant's hover colour outranked the pressed and lit colours: the state layer stands down on [data-lit] and those colours are important. The menus' Play from the beginning wears RotateCcw like the card's Restart, Reset wears Eraser and Redownload the retry arrow (DESIGN decision log). Tests pin the toggle's orders, the Watch later mark at its call sites, the live-search overrides, the hover exemptions and the menu glyphs.
