Visual fidelity round 2

CSS:
- Wrap all background-image url(...) in {{ ... | relative_url }} so home
  banner, sprite word art, footer bars, and arrow icons resolve under
  the project baseurl.
- Bump primary nav letter-spacing 0.08em -> 0.22em to match original.
- Footer: drop generic dotted border in favor of two-tone bars (dark
  gradient + teal block) sliced from nav_banners.png, aligned with the
  hero banner's photo-vs-tab split.
- Resources: drop the per-row left-column word-art slot (which left
  awkward whitespace on rows 2-3); pull the 'On-line Resources' word
  art out as a flush-left header above all rows.
- Resource dividers reworked from border-bottom + :last-of-type to
  border-top with adjacent-sibling combinator so dividers only appear
  between items.
- Publications: support for thumb when a featured pub has one (via
  :has(.pub-thumb) layout switch), pipe-separated link list, dotted
  divider between entries.
- PubMed link: drop inline-flex (was inserting gaps between text nodes
  and <strong>); use inline-block icon, underline + accent color so it
  reads as a link.
- Person card: add .person-links for CV / Stanford profile under role.
- Show all .imgsp_more_* anchors transformed to plain 'Read more →'
  links (handled in scraper).

Content / scraper:
- Featured publications now scraped (~40 added; 138 -> 177 entries).
  Detect title from <span class='contactH1'> as well as <u>; mark
  featured: true; capture thumbnails from sibling <td>.
- Collect Preprint / Server / Code / etc. links into per-pub link arrays
  (link_labels + link_urls), rendered after Paper / Link.
- News scraper: strip the leading <p class='yearTEXT'> date paragraph
  (was duplicating the date), and rewrite empty btn_readmore anchors —
  which were producing a stray '</a>' on the index — into clean
  'Read more →' links.
- Alumni & current-people roles: collapse 'Role , year' -> 'Role, year'.

People:
- Update Rhiju's photo to a higher-resolution recent shot.
- Add CV (Dropbox) and Stanford profile links beneath name + role.

News index: show 10 recent items, hide the rest under 'Previous news'.
Author truncation bumped 600 -> 1200 chars.
