UX iteration after first live look:
- Sticky anchor strip below the header with a chip per section (incl.
Submissions) so staff can jump around a long page.
- Compact one-line rows that show only the latest value; multi-history
fields get a muted 'N earlier entries' toggle that reveals the rest
inline. Same affordance for file fields.
- Empty fields collapse under a single 'N empty fields' toggle per
section instead of taking a row each.
- Stage 5: Y1_Q<n>_<metric> fields render as a read-only matrix table
(rows: metrics; columns: Q1..Q4) matching the form's matrix layout.
File proxy (/api/staff/file) deleted. APIv4 Attachment isn't exposed
on this Civi instance (per the June upload spike), which is why the
previous proxy returned broken images. Staff are already authenticated
to Civi when they arrive here, so file fields now render as outbound
links to CIVI_BASE_URL/civicrm/file?reset=1&id=<id> and the browser
uses the staff session. No more proxy auth, no more SSRF surface to
harden, no broken images.
CIVI_BASE_URL flows from the staff page (server component) into the
client as a prop. No secret material crosses the boundary.
- Allowlist inline MIME types (png/jpeg/gif/webp/pdf only); everything
else, including SVG and HTML, served as application/octet-stream
with content-disposition: attachment.
- X-Content-Type-Options: nosniff and a restrictive CSP on every response.
- Validate the upstream URL Civi returns: must match CIVI_BASE_URL origin
before we attach basic-auth creds and follow it. redirect: manual to
prevent off-host hops.
- Drop SVG from the client's inline-image list (server forces download).
