Nasal coda class, go-live polish, mobile layout, hardening

Browse Source 
- M/N/NG merge in consonance keys (damn/hand/plans, time/line); vc
  consensus lets vowel-founded groups advertise an agreed coda
- Meta description, OG tags, orange favicon, theme-color
- Mobile: single-column layout, panel stacks under the editor
- /healthz, 100k-char draft cap, lookup length/limit caps
- Internal fills brightened (19%, ends stay 34%)
