build/Now.hs renders the .now-stamp-relative phrase ("3 days ago") at
build time against the build machine's clock; a page served days later
from cache or a CDN would then read stale. now.js recomputes the
phrase in the browser from the <time datetime> attribute (an
unambiguous YYYY-MM-DD) against the visitor's clock, with bucket
thresholds that mirror Now.hs:relativeTime exactly so the no-JS
fallback and the recomputed value agree.
* static/js/now.js — the recomputation script.
* templates/default.html includes it via $if(now)$ so it only loads
on the Current page.
