Initial commit: dlstack file-driven link index

A hand-rolled linktree alternative — pure static HTML/CSS/JS, no build
step. Drop on any shared host via SFTP and edit data/links.json to update.

Features
- File-driven content via data/links.json (links, projects, YouTube,
  client tiles, portfolio pieces)
- Two interchangeable templates: editorial (Fraunces + paper + vermilion)
  and swiss (Archivo grotesque, all-caps poster)
- Auto/light/dark theme toggle with no-flash boot script
- Auto-fetched favicons via Google S2 (with image-URL override)
- Lazy YouTube facades (no third-party JS until clicked)
- Adaptive client-logo grid
- Scroll-triggered reveal animations
- ~40 KB total payload, ~12 KB gzipped

The repo ships links.example.json as a demo; data/links.json is
gitignored so personal content stays out of the public repo.
