Release 4.219.0

Every plain element styled by the theme (the owner, 11-12, with circled screenshots of openvibe.exchange: "make sure all basic elements are styled … custom with the theme system … update the little dots … reflect and improve all existing elements … the spacing could be improved").

• Radios and checkboxes are drawn under .ov-base: a ring in the theme's line colour, the site's fill when chosen, the radio's dot growing in and the checkbox's tick popping in (Calm keeps the change, Off removes the movement), a focus ring, and a label that holds its control is one tappable row.
• Text fields: the placeholder in the muted colour, an accent ring on focus, room under each field.
• A plain details (no class of its own) gets a chevron that turns when it opens, and no browser marker; a site's own details keeps its own.
• A site's own questions in a showcase section (a plain <details> straight in .sc-sec, as 20 homes have them) look like sc.faq's: a card each, no browser marker, a chevron that turns, the answer padded (unstyled-sweep found them on Blog, Chat, Compare, Coupons, Deals, Download, Food, Games, Host, News, OpenRestream, Reviews, Run, Space, Tips, Trade, VIP, Vision, Wiki and Zone).
• Words straight in a kit section (<p>, <a>, <details>, lists, quotes, code) keep the section's padding; they sat flush against the box's edge.

Test: kit-layout-chrome (the drawn radio and its dot, the filled checkbox, the plain summary's chevron, a section's padding).
