GET /campaigns/:id/recipients/:i/view re-renders the campaign with the
same vars the worker used at send time — same template, same per-row
amount override, same language pick. Useful when the recipient's mail
client butchers the layout: image-blocking, antique Outlook, niche
third-party apps, accessibility tools.
Templates: Mustache section {{#view_url}}…{{/view_url}} guards a tiny
gray link above the header logo (11px, #94a3b8). The section collapses
to nothing when view_url is empty, so:
- the /view page itself doesn't show the link (you're already there)
- wizard previews / test-sends don't show it (no real campaign id)
worker passes view_url = HUB_PUBLIC_URL + /campaigns/<id>/recipients/<i>/view
using the existing cfg.HUB_PUBLIC_URL setting (defaults msg.gigafibre.ca).
Security: campaign-id is a 21-char nanoid (≈10²¹ space). Same level of
exposure as the Giftbit shortlink itself. X-Robots-Tag: noindex on the
response so the URLs don't end up on search engines.
