papers/platter: restore the original /platter, add jeffrey + opinions
I overwrote /platter (the white research-records page at platter.html)
with my own dark-themed dir index. Reverting that — the original page is
the right home for the platter overview, and the new content (Jeffrey's
Instagram link, opinions list) belongs as sections inside it.
- Delete system/public/papers.aesthetic.computer/platter/index.html
- Caddyfile: replace /platter→/platter/ permanent redir with
/platter/→/platter 302 to invalidate the cached 301; keep
/platter/jeffrey→/platter/jeffrey/ permanent so the dashboard's
relative manifest fetch still works
- platter.html: add Dashboards section linking to /platter/jeffrey/
and Opinions section listing the four .md essays directly (raw
markdown URLs, per request — not the AC pixel-text rendered version)
Also: jeffrey dashboard now uses full-quality originals in BOTH the
grid AND the lightbox (was thumbs in grid, full in lightbox). Browsers
lazy-load and cache, so the per-image cost is paid once on first scroll.
