Inline comments:
In `@docs/components.mdx`:
- Around line 161-162: The docs page mixes framework-specific Next.js wording
with framework-agnostic language; update the table entries that mention
Next.js/`<img>` to use neutral phrasing: change the HTML row that references the
`<img>` tag and any line containing “Next.js optimized” to instead say
“optimized Image component” (or similar neutral copy) for local images and
“standard <img> tag” for external images so the page consistently uses
framework-agnostic wording; locate and edit the table cell text matching the
strings "Local images — Rendered with optimized `Image` component (default
800x400)" and "External images — Rendered with standard `<img>` tag" and the
HTML `<img>` row to ensure consistent phrasing.

In `@docs/frontmatter.mdx`:
- Around line 83-87: Update the frontmatter docs to constrain the lastModified
field to a strict ISO-8601 format because the sitemap generation uses new
Date(...).toISOString(); change the description for the lastModified entry (the
"lastModified" frontmatter key) to require either a date-only format
(YYYY-MM-DD) or a full ISO datetime (e.g., YYYY-MM-DDTHH:MM:SSZ), and add one or
two examples showing both allowed formats so consumers know what to pass.

In `@packages/chronicle/package.json`:
- Line 54: The package.json currently pins "nitro": "3.0.260311-beta" which is a
pre-release; either change the dependency to the latest stable "2.13.2" or add a
short justification and testing note in the repo (e.g., in README or CHANGELOG)
explaining why Nitro v3 beta is required and listing compatibility checks
performed (Vite/Nitro integration, Node v20 requirement, import/path changes,
cloud provider bindings); update the "nitro" entry or add the justification
referencing the package.json "nitro" key and any test scripts or docs you used
to validate the beta.
