browser+resize: implement proper faux browser + resizable windows per design handoff

Browser window (w-browser, Internet icon):
- Full aqua browser chrome: toolbar with back/fwd/reload/home SVG nav buttons,
  URL bar (lock + scheme + host + path + blinking caret), bookmark chips
  with colored 12x12 favicon squares, scrollable page surface, status bar
  with animated progress bar
- History stack (back/forward state, disable at ends)
- Delegated click handler via data-go attributes for in-page navigation
- Refresh button spins 700ms via CSS animation
- Address bar + title bar update on every navigation
- ARTICLES array with 4 entries (self-hosting, jazz, cooking, film) with
  drop-cap, Georgia body, IBM Plex Mono metadata, blockquotes, inline ilinks
- Chrome theme: brushed mercury toolbar, dark navy article surface with
  iridescent radial hotspots, Audiowide titles with chromeShimmer drop-cap,
  Michroma UI labels, iridescent progress bar, custom scrollbar

Resizable windows:
- makeResizable() in aero.js: appends .rs-e (right edge), .rs-s (bottom edge),
  .rs-se (SE grip) handles; tracks mousedown/move/up; enforces minW/minH
- .win.resized flex-column flip: body fills remaining height and scrolls
- Aero grip (3-stripe diagonal, blue); Chrome grip (iridescent purple/cyan/pink)
- Body cursor forced via body.rs-cursor-* classes during drag

CSS in aero.css: chrome overrides for resize handle + full browser window theme
CSS in index.html: resize handle rules, full browser/article reading styles
