CSS preload error banner shown on Browse Tables, Lab Panels, and Persons pages #69

Description

Problem

A red error banner appears at the top of admin/list pages instead of (or alongside) the data table.

Steps to reproduce:

  1. Open Browse Tables (table: AnalysisSeries), or Lab Panels, or Persons.

Actual:

Error: Unable to preload CSS for https://<host>:8080/static/css/DataFrame.DUkanX9_.css
  at HTMLLinkElement.<anonymous> (https://<host>:8080/static/js/index.dkY5s53S.js:100:2588)

Expected: No error banner; the data grid renders normally without a broken CSS-preload warning.

Seen on the deployed dev instance (132.203.190.77:8080) on 2026-07-30, same error text on all three pages — likely one shared root cause (a stale/hashed asset reference in the built frontend, or a preload <link> pointing at a filename that no longer matches the deployed build).
