Archived practice: explain the note limit

Earlier exercise

The current assignment is Rock, Paper, Scissors. This page preserves PRACTICE-001 from the earlier link-library exercise. It is not another task to complete.

PRACTICE-001 remains unfinished in the instructor's link-library repository. Prior trials implemented it in separate repositories.

Purpose

Help someone understand what they can put in the optional Note box.

Feature

ID	What should change	Expected result
PRACTICE-001	Explain the note limit beside the field.	“Add a short note (up to 4,000 characters).” appears directly below the Note box before typing. The field is associated with its help text.

Examples to try

• Open the app: the sentence appears below Note.
• Save https://example.com with a short note: saving still works.
• Save that URL again with a different note: the existing entry opens and keeps the original note.

Decisions and limits

Keep the existing 4,000-character limit. Change only help text and its HTML association; no new validation, database behavior, summaries, or other features.

The relevant file is app/public/index.html. Start with a plan before editing.

Work and checks

Feature	Issue	Implementation	How to check
PRACTICE-001	Add your own issue URL.	Not implemented in this starter.	Not verified for your change.

In your repository, replace this row with your issue, implementation link, and what you actually checked. LINK-001's existing tests check saving; they do not establish that the new help text appears correctly.
