Lightning Web Component Form

I need a purpose-built Lightning Web Component that focuses exclusively on gathering user input through a LWC Record edit form and processing that submission cleanly inside Salesforce. The form layout is ready.

Key points
• Front-end: LWC (no css only slds) is ready
• Back-end hook: May not require as the js can handle the logic
• UX: Field-level validation, toast notifications on success/failure, and a loading spinner while the save action runs.
• Packaging: include the metadata files for easy SFDX deployment and a brief README that tells me where to place the component and how to update labels.

Acceptance criteria
1. Submitting valid data triggers the Apex method and surfaces a Success toast.
2. Invalid data prevents submission and surfaces inline error messages.
3. Code passes Salesforce security scan (no “@AuraEnabled cacheable=true” on mutating calls, no unsafe eval, etc.).
4. All files compile and deploy via SFDX without manual tweaks.

Deliverables
• Complete LWC bundle (.html, .js, .js-meta.xml, optional .css)
• README with deployment and extension instructions

If you already have sample code or a preferred validation pattern, feel free to mention it—otherwise I’m open to whatever you believe is best practice.
