v1.3.0 — Sourcefolio: portfolio homepage

The theme has a name now — Sourcefolio 🎉 — a personal portfolio and blog
theme for Ghost, based on Source. This release turns the homepage into a
portfolio-style landing page that anyone can reuse.

What's new

🏠 Portfolio-style homepage

• Intro hero — name and tagline (from site title & description), a round
  avatar, pill-style links (job, LinkedIn, GitHub…), and a "Read more" link to
  your about page
• Fully editable from Ghost Admin — hero paragraphs, pill links (via an
  HTML card), and the avatar all come from a page with the slug home; no
  template edits needed. See the README's Homepage setup guide.
• Featured posts only — the homepage feed lists posts marked as Featured,
  with a "See all" link to the full archive at /blog/

📦 Rebrand & metadata

• Theme renamed source → sourcefolio; version now tracks these release tags
• Theme zip is now sourcefolio.zip; package metadata points to this repo
• README rewritten with a setup guide for new users

🧩 Theme internals

• New featured feed mode in the post-list component
• New github and briefcase icon partials
• Removed unused header_text and background_image custom settings

Upgrade notes

• Uploading sourcefolio.zip installs as a new theme in Ghost Admin —
  activate it and remove the old source-named theme
• Create a published page with slug home (feature image = avatar, HTML card
  for pill links — see README), and mark the posts you want on the homepage
  as Featured
• Make sure routes.yaml is uploaded (Settings → Labs → Routes)
