Release 4.243.0

One + everywhere, and a menu that knows who is looking (the owner, 11-13: "I don't really like the plus … way more animated, better effects"; "user aware and session aware and … aware of rank … user can through API and SDK read it … more mobile friendly").

• The menu's + is the composer's. The Ask bar's attach button wears the same mark as the composer: two arms over four petals that peek under the pointer and burst outward on a tap as the file picker opens, the arms turning a quarter and settling back. Calm slows the bloom and shortens its travel; Off stills it (rule: Calm reduces, only Off removes).
• The viewer model (plan §Z.2). OpenVibeNavbar.viewer(), also OV.viewer(), says who is looking: signed in or a guest, the rank (member, streamer, mod, admin), staff, the owner; how long this visit has run (kept per tab); and the device (phone, touch, installed, the motion setting). The navbar writes it on <html data-ov-viewer="guest|member| staff|owner" data-ov-rank="…">, so a site's CSS can adapt its nav, and fires openvibe-viewer on window when it changes (a sign-in, a sign-out, never a re-render). Nothing in it leaves the page. The id is the person's usr_ subject; apps and servers read the same model from Network's GET /api/v1/viewer.
