feat: tag checkout platform source

## Summary

Small follow-up to #13289 applying two non-blocking review nits from
Alex's review.

## Changes

- **What**: drop the redundant `before:content-['']` on the
customer-story list bullet (Tailwind emits the empty `content`
automatically once another `before:` utility is present), and rename
`HEADER_OFFSET` to `HEADER_OFFSET_PX` in `ArticleNav` so the scroll
constants use consistent unit suffixes.

## Review Focus

Both changes are cosmetic with no behavior change. Confirmed in the
browser that the list bullet still renders identically (6px yellow dot)
without the explicit `content` utility.

## Notes from the #13289 review (left as-is here, open to discussion)

Three other comments from the review are intentionally not changed in
this PR; reasoning below so the decisions are on record:

- **`Category` type in `ArticleNav`**: kept the `ComponentProps<typeof
CategoryNav>` derivation. AGENTS.md says to derive component types via
`vue-component-type-helpers` rather than redefining them, so the current
form follows the styleguide. Happy to switch to a plain named type if
preferred.
- **Section ids in frontmatter vs the body `<Section>`**: kept the
`customers.content.test.ts` parity test. The short TOC labels live only
in frontmatter and Astro can't introspect the rendered MDX body to build
the nav, so the frontmatter `sections` list and the body anchor ids
can't be trivially deduplicated. A real fix would need a remark plugin
(larger, separate change). The test guards against silent drift in the
meantime.
- **`nextStory` throw**: left as a fail-loud, build-time invariant. The
slug always comes from the same `getStaticPaths` collection, so the
throw is effectively unreachable; it surfaces a future-refactor bug
loudly instead of linking to the wrong story.
