## I have read the

file.
YES
## Problem
From Linear:
Accordion usage in the docs is inconsistent and can render with double
lines instead of single lines.
The current docs contribution guidance appears to recommend wrapping
accordions with an extra div, which seems to be the cause of the extra
divider in some pages.
## Solution
This PR:
- Removes all wrapping `divs` to AccordionItems that adds an extra
border
- For a11y, adds a cursor pointer and a slight bg color change on hover
to make the clickable area more obvious
- For a11y, adds reduce-motion option for animation and `aria-hidden` on
the chevron
**Note:** It is good for a11y to have more than one hover-state
indicator. For example, color-change and an underline.
## Tophatting
To review changes on the preview environment:
1. Go to `/docs/guides/platform/backups` and
`/docs/guides/platform/migrating-to-supabase/auth0#frequently-asked-questions-faq`.
2. Expand accordion.
3. See nothing visually odd such as strange spacing or double borders.
**Note:** To be exhaustive in your review, view all affected URLs and
scan the docs for `border-b` to see if there are any stragglers.
