Related Issue

resolves #1253

Summary of Changes

1. Refresh the init template landing page with simple custom element example and better link documentation

To test, run

$ cd packages/init/src/template
$ npx @greenwood/cli@alpha develop

TODO

1. continue tweaking animation by centering the leaf / refactoring class names
2. Handle FOUC on the logo
3. odd styling issue at tablet breakpoint
   
4. validate / update test cases
5. Handle loading Geist font (do we need / want it, just use system font?) - system font is fine
6. Add website links (this might come before the new website, so may have to create a tracking item for all links that need to get changed)
7. get final logo - update Greenwood logo with official logo from original source assets www.greenwoodjs.dev#47
8. validate build / serve tasks
9. 🚨 need to "downgrade" our usage of import attributes per polyfill configurations for import maps and attributes #1268

Tracking Items

1. remove default Greenwood layouts content - remove default content (pages / layouts) from Greenwood  #1271
2. New Prompts for TS / markdown support - init scaffolding should prompt for installing common plugins (TypeScript and markdown) #1270
   • markdown needs - standalone rehype based markdown plugin #1247
   • can probably account for refactor init package #1050 / restore Init package --install based test cases #787
3. pnpm support - expand package manager options for init scaffolding #1272

Questions

1. should greenwood even have default layouts? - Per our meeting, probably not?
