Includes:
Sidekiq::Worker
Defined in:
app/workers/article_pdf_worker.rb

Overview

Generates an article PDF in a Sidekiq process (outside Passenger workers) and
attaches it to an existing Communication, then optionally queues/releases the
communication for delivery.

Playwright/Chromium-based PDF generation is memory-intensive (~200-300 MB per
render). Running it in Sidekiq isolates that cost from the web process pool.
