landing: structured feature groups, single-source comparison table (#11)

- The ~1,800-word fork paragraph becomes 7 titled groups, one short line
  per feature, plus a link to LOTUS_FEATURES.md.
- Single source: landing/data/features.json + comparison.json, rendered
  into index.html by landing/build.py between BEGIN/END markers (all 71
  table rows re-render with identical cell text).
- CSS moved to landing/style.css; build.py inlines it because the LXC 139
  deploy copies index.html only.
- "Client comparison last reviewed" stamp driven by comparison.json.
- CI job `landing-fresh` fails if index.html drifts from its sources.
- Feature list brought up to date: 629 avatar decorations in 28
  categories, mic level meter + remembered per-person volume, search
  operators, paste-as-code, thread "Mark all read", pinch-zoom/swipe media
  viewer, room widgets with a permission prompt.

+"""Render the data-driven sections of landing/index.html.
+
+The fork feature list and the client comparison table used to be edited by
+hand in two places per feature (matrix #11). They now live in landing/data/:
+
+  features.json    - the "our fork adds" groups, one short line per feature
+  comparison.json  - the client comparison table + its "reviewed" date
+
+and the stylesheet lives in landing/style.css. It is inlined into index.html
+rather than linked, because the LXC 139 deploy copies index.html only.
+
+Run `python3 landing/build.py` after editing either file and commit the
+regenerated index.html (LXC 139 serves the files as-is; there is no build step
+there). `--check` exits 1 if index.html is out of date, for CI.
+
+Only the text between `<!-- BEGIN:name -->` and `<!-- END:name -->` markers is
+rewritten; everything else in index.html stays hand-edited.
