Release 4.202.0

One field dropdown, one window for small interfaces, one user card, a measured page end, eight site groups, and the reveal remade.

• An empty footer column is never drawn (footer.js). A group with no heading or no links is left out instead of showing as an untitled "0 links" fold.
• One field dropdown (#447). ov-combo.js adds async, grouped suggestions and optional creation; the composer handoff to Code and whole site names in the phone menu are included.
• One window (#451). ov-window.js supplies dialog, sheet and panel modes, and the composer's settings use it.
• One user card (#452). Shared mention hooks, the profile card, wallet window and display style settings.
• Page end (#442). A shared bottom measurement keeps the end of a page at 32 px on computer and 24 px on phone.
• Eight site groups (#445). The footer, rooms, You folders and home pages use the same groups.
• Reveal (#448). Headings emerge from blur, rules draw, and up to six cards stagger as they enter view.
• Jump back in (#412). The full history link and private history support are present from the 4.201.0 base.
