Add issue No. 02 "Obsession" + reusable image pipeline

Content
- 100 new plates under content/posts/02/ — one recurring red-haired model
  across 10 editorial registers (Haute Couture, Film Noir, Boudoir,
  Avant-Garde, Minimalism, Baroque, Street Style, Surrealism, Monochrome,
  Nocturne), generated with flux-1.1-pro, face-swapped to a consistent
  identity (FaceFusion), and upscaled (Upscayl + Remacri, 3328x4992).
- content/issues/02/_index.md; issue 01 -> status archived; hugo.toml params
  (issueIds newest-first, issueNumber/Name/Season/Blurb).

Structure
- Plate bundles grouped by issue: content/posts/<issue>/<slug>/, with
  build.render:never stubs so /posts/<issue>/ isn't emitted. nginx 301s the
  legacy flat /posts/<slug>/ URLs to /posts/01/<slug>/. The /posts/ archive
  uses .RegularPagesRecursive.

Image pipeline (scripts/, data/ gitignored)
- generate-images.py  — Replicate flux-1.1-pro, 960x1440, idempotent.
- faceswap-images.py  — FaceFusion batch-run, one consistent face.
- upscale-images.py   — Upscayl + remacri-4x, long edge clamped to 4992.
- build-issue.py      — prompts JSON -> content/posts/<issue>/*/index.md.

Build
- CSS now compiled by Hugo's css.TailwindCSS (partials/css.html +
  templates.Defer); dropped the standalone Tailwind CLI step, concurrently,
  and the gitignored static/css/main.css. Requires Hugo >= 0.161; Dockerfile
  collapsed to a single hugomods/hugo:debian-node build stage.
  pnpm-workspace.yaml: preferSymlinkedExecutables + allowBuilds.

Front end
- Pagination 8 per page.
- Lightbox: brand mark and category link out; robust SPA back/forward
  (fetch before startViewTransition, single-flight guard, swallow the
  transition abort rejection, popstate re-renders / reopens the viewer).
