2026-02-23 — Layout polish (dark mode + branding)

Changes made on branch layout-fixes-2026-02-23:

• Dark-mode typography fix: Updated style.css so hard-coded heading and listing-title link colors apply only in light mode, and dark mode inherits colors from the Quarto darkly theme. This prevents low-contrast headings/links in dark mode.
• Navbar shadow in dark mode: Increased the shadow alpha for .navbar in dark mode to avoid a washed-out/light haze.
• Branding consistency: Aligned website.navbar.title with website.title in _quarto.yml.
• About page content: Expanded about.qmd with a short description of the blog and what readers can expect.
