In `@__tests__/applications/applications.test.js`:
- Around line 75-94: The interceptor branch matching url
`${STAGING_API_URL}/applications/lavEduxsb2C5Bl4s289P` contains an unreachable
non-GET branch because submitApplicationFeedback issues a PATCH to the
`/feedback` suffix; remove the dead code by deleting the conditional branch that
handles method !== 'GET' (the JSON response with message 'Application feedback
submitted successfully') inside the interceptedRequest.respond block for that
exact URL, leaving only the GET response that returns pendingApplications[0];
ensure the actual PATCH handler remains in the separate interceptor that matches
the `/feedback` URL so submitApplicationFeedback is still tested.

In `@applications/index.html`:
- Around line 135-140: Update the Request changes button so its aria-label
matches the sibling buttons' pattern and casing: change the aria-label on the
element with class "application-details-request-changes" to "Request Application
Changes" (and ensure the visible button text follows the same capitalization if
needed) so it consistently uses the "[Action] Application" format like the
Accept and Reject buttons.

In `@applications/script.js`:
- Around line 281-283: The textarea's placeholder is never set because the
property is named "placeHolder" (wrong casing); update the element creation to
use the standard "placeholder" attribute (e.g., change placeHolder to
placeholder or call setAttribute('placeholder', 'Add Feedback here (required for
Request changes)')) in the code that builds the element (where the object with
placeHolder and innerText is used) so the browser renders the hint correctly.
- Around line 178-185: The Score and Nudge Count sections render the literal
"undefined" because createElement sets element.textContent to
application.score/application.nudgeCount even when they are undefined; update
the code that builds these sections (where application.score and
application.nudgeCount are used) to guard against missing values by either (a)
only creating/pushing the section if the value is not null/undefined, or (b)
coerce the value to a safe display string (e.g., empty string or "—") before
passing it into createElement; reference the createElement helper and the
application.score and application.nudgeCount usages to locate and apply this
conditional check.

Outside diff comments:
In `@applications/script.js`:
- Around line 229-263: The forEach loop parameter named application shadows the
outer openApplicationDetails parameter; rename the loop variable used in
selectedApplication.applicationDetails.forEach (and its internal references like
application.title, application.description, applicationSection,
applicationSectionDescription) to a nonconflicting name such as detail or
appDetail, update every use inside that loop accordingly, and leave the outer
openApplicationDetails binding and the separate status-check logic untouched so
there is no variable shadowing or potential future confusion.
