Markdown Preview for Jira

``` Someone attaches a design doc, a runbook, or release notes to a Jira issue as a .md file. Today that means downloading it, finding it, and opening it in another app — and doing it again every time the file changes. This extension renders it where it already is. Open the issue, click the button in the bottom-right corner, and the file opens on top of the issue, formatted. WHAT IT RENDERS • GitHub-flavored markdown — tables, task lists, strikethrough, autolinks • Syntax highlighting for around 40 languages • Mermaid diagrams, redrawn when you switch theme • Math, inline and display • GitHub alerts — NOTE, TIP, IMPORTANT, WARNING, CAUTION • YAML front matter as a table instead of a stray horizontal rule WHILE READING • A table of contents that follows your scroll position • Light and dark themes, and adjustable text size • Copy the raw markdown, or any single code block • Export a standalone HTML file, print, or pop the preview into its own tab • Esc closes it. Alt+Shift+M opens it from the keyboard. WHY AN ORDINARY MARKDOWN VIEWER DOESN'T COVER THIS Other markdown viewers wait for you to navigate to a .md file, then render that page. That never happens with a Jira attachment: Jira serves attachments as a download rather than a page, the URL is an opaque id that redirects to a signed media host, and the issue view shows attachments as cards rather than links. So the usual approach never fires. This extension goes the other way round — it reads the issue's own attachment list, fetches the file with the session you are already signed in with, and renders the result. PRIVACY Nothing is collected. No analytics, no accounts, no telemetry, no servers of any kind. Every library is bundled inside the extension, so no code is fetched at runtime. The extension only runs on Jira domains, and the only requests it makes are to your own Jira site: the issue's attachment list, and the one file you click.
