Give projects and members their own pages

The API has always served a project's and a member's detail, with
`path` and `alternates` in three languages, and the site had nowhere to
show it. A project now has its page — tagline, status, technologies,
description, technical decisions, what was learned, gallery, client,
dates, lead, team, repositories and open calls — and so does a member:
headline, bio, links, technologies and projects. Cards on the landing
link to both.

Addresses follow the API's rule read backwards (core/routes.ts):
pages at the root, records under a section named in their language,
the default language unprefixed. One catch-all route serves them all.
Not a route per shape: Analog registers each loader as an internal
Nitro route, and Nitro's router cannot hold `/:prefix/:slug` beside
`/:prefix/:section/:slug` — the first became unreachable.

The frame around a record (header, footer, lights, 404/503, title,
description, canonical, hreflang) is one component now, PageShell, and
each type only brings its body, all sharing one layout partial.

Also fixes chips that stepped down one row after the first, on the
landing's cards too: @pi/ui's reset gives every `li + li` a top margin,
right for prose and wrong for a row spaced by `gap`.
