Until an observer has started on new code, a read of a column it adds fails with Postgres 42703; the three public
handlers now answer 503 "the observer has not been restarted on the explorer code yet" instead of 500, and the pages
show it. The Circulating tile reads "cap 4,000,000,000, 3.96 billion ever minted" with the withheld figure on hover;
the homepage tile and the litepaper keep the project lead's words (consequences-decisions D3, D7). The live observer was restarted
on this code at 19:42:50 UTC by another session; its counters are in the plan.
