bench-kit 1.9.3

• Book: Share highlight (David, via kuki): while a passage's highlight link is held, ✦ Share highlight in the toolbar makes a picture to send: the page with the passage's place drawn on it in the links' colour, the passage beside it, and under that the page's name, the text, the citation, the bench and the image's credit (and, for an estimated place, that it is approximate). In the order David gave: Copy link gives a link that opens Book with the same highlight held (hr: the page, the place and the first of its words, so a place is found again after its file is remade); Email… hands the picture and the passage to the system's sharing where the browser can pass a file, and elsewhere starts a message with the passage, the citation and the link, with the picture copied to paste in (a page cannot attach a file to an email); Download PNG and Copy PNG give the picture.
• Book: Share is Share page (David): the toolbar's link to Book as it is set, as before, under the name that tells it from Share highlight.
• Edit's text in a box of its own (David, via kuki): Edit set the file's text in the same face on the same ground as the pages of Book, with only the padlock in the toolbar to tell them apart. The text is now in a field with a head: greyed, with a plain edge, while locked; white (in a dark theme, the lighter surface) with an edge in the bench's accent once unlocked. The head says which, and what the box holds (the text as its file has it, Markdown), and its padlock locks and unlocks as the toolbar's does.
