Release 4.212.0

A train of four pull requests (one line each):

• A carried Live player can play on any OpenVibe page that permits Network frames. The portable card keeps the original Live embed and channel addresses in its state, while its iframe loads Network's narrow Live player bridge; sound controls and state events pass through that frame, so no destination's frame policy changes (#473, ask 360).
• The bar catches up on balance changes across sites (ask 273). Once a signed-in wallet loads, its pill plays each currency's net gain or loss once and marks that currency's cursor read through Network's frame relay; Calm keeps one quiet effect, Motion Off updates the figures only. The Wallet sheet starts with the recent net amounts and the API's plain reason names (#474).
• The Dock's pill stands above a page's bottom composer. bottom.js measures a composer docked at the bottom of the screen (form[data-ovt-composer] or data-ov-bottom-dock) and writes --ovb-composer; the pill keeps above it as it grows and comes back when it goes (on openvibe.chat it covered the send button) (#475).
• Glyphs: focus and bridge redrawn after the all-glyph review: focus is a viewfinder round its centre, bridge two towers, the cable and the deck; both have solid twins, drawn to the set's size (the long side 0.79 of the box); the drop-in, sprite and fonts are rebuilt (#476).
