accessibility, and unify SVG fill color to #fff
Update BaseLayout to use a header <p> for the website title, rename the
main slot/id to
"main", and update all pages to match. Add CSS rule svg { fill:
currentColor }
and size header > p the same as h1. Fix a minor comment typo.
Introduce reset.css and theme.css and refactor style.css
to import them via layers; add Unscii font files and preload links.
Add RSS XSL/CSS and a css-test page; remove legacy snes.min.css.
Tweak BaseLayout and contact layout (preloads, grid gaps). Rename index.astro to parallax.astro and
created new basic index page. Improve input styles and contact form placeholders
