- Rename `effect` variable to `eff` in editor.ml (reserved keyword in 5.4)
- Add `first_crc` cppo-guarded helper for cmi_crcs API difference
(Import_info.t array in oxcaml vs (string * Digest.t option) list in 5.4)
- Remove `source_rendering` from dune-workspace (not in upstream dune/odoc)

All extension packages, tessera, zarr, and odoc now build with both
oxcaml 5.2.0+ox and standard OCaml 5.4.1. The js_top_worker library
compiles on both; linking requires matching merlin-lib.

Three fixes for "Position N is out of range for changeset" errors:

1. js_top_worker: clamp output_at loc to input length — the ";;"
appended for parsing made pos_cnum extend past the original source

2. x-ocaml/editor: clamp decoration positions against CM document
length (Text.length) not OCaml String.length — they differ for
non-ASCII text (UTF-16 vs bytes). Also combine doc replacement +
decoration clear into a single transaction in set_source, and
read actual CM doc in build_range_set

3. jsoo-code-mirror/decoration: defensive safe_map that catches
JS RangeError in RangeSet.map and returns empty

The js_top_worker-widget-leaflet library is wrapped, so #require
only registers Widget_leaflet as a toplevel module. Leaflet_map
is a submodule and needs open Widget_leaflet to be in scope.

When a cell contains multiple let bindings without ;; separators,
the OCaml toplevel groups them into a single Ptop_def with multiple
structure items. The output_at loc was using the first item's
pstr_loc, placing all val outputs after the first definition.

Now uses the last item's loc so output appears after the final
definition in the group.

Dot extension: Replace per-diagram Js_inline scripts with a single
Js_url support file (dot-init.js) using MutationObserver pattern.
Store DOT source in <script type="text/dot"> elements to avoid
escaping issues. Fixes SPA navigation rendering.

Merlin config: Add stdlib path to build_path so dynamically loaded
packages (e.g. cmdliner via #require) resolve in merlin's type
checker. Previously only stdlib was set, causing red squiggly
errors on library references despite code compiling fine.

Widget_leaflet: Re-export Leaflet_map module from Widget_leaflet
so it's part of the public API. Add leaflet widget demo page.

Interactive extension demos: Move broken demos to .notyet:
- demo2_v2/v3: fake v1/v2 distinction (same cmdliner version)
- demo3_oxcaml: comprehensions extension disabled in compiler
- demo4_crossorigin: requires jon.ludl.am infrastructure
- demo5_multiverse: requires localhost:9090
- demo6/demo7: porting workshops need work

Fix demo_map and demo_widgets: add @x-ocaml.universe and
@x-ocaml.worker tags pointing to /_opam.

Simplify build-site.sh: remove redundant v2/v3 universe builds.

Sidebar: Add odoc-md to 'odoc Core' package group.

Scrollycode: Remove theme references from docs, align titles.

build-site.sh: Use dune-built worker.js (--no-worker + cp) so the
worker always matches the source tree. Previously jtw compiled against
the installed js_top_worker-web package via ocamlfind, which could be
stale. Also make @site and @doc steps fail on errors instead of
swallowing them.

js_top_worker: Add blank_directives to strip #require lines from source
before sending to merlin. The pre_source context prepends previous cells'
source (including #require directives) which causes Menhir's incremental
parser to throw force_reduction errors.

x-ocaml: Add bounds checking to Typed_enclosings response in
merlin_ext.ml, matching the existing pattern for Errors. Prevents
CodeMirror RangeError when merlin returns positions outside the cell's
document range.

odoc-mermaid-extension: Fix SPA navigation by replacing Js_inline init
script with Js_url support file using MutationObserver pattern. The old
startOnLoad:true approach only worked on full page loads; now mermaid.run()
is called explicitly whenever new pre.mermaid elements appear in the DOM.

site/dune.inc: Regenerated with --warn-error on odoc compile/link/
html-generate, and -L/-P flags for library/package cross-references
from @doc build output.

Leaflet_map provides a type-safe OCaml interface to the Leaflet widget:
- Leaflet_map.create: typed config (center, zoom, height) + typed callbacks
(on_click receives latlng, on_bbox_drawn receives bounds)
- Leaflet_map.add_image_overlay: typed bounds + url + opacity
- Leaflet_map.add_marker: typed latlng + optional color/label
- All JSON serialization hidden inside the wrapper

The notebook no longer uses raw Widget.command/Scanf.sscanf for map
interaction. Compare:

Before: Widget.command ~id "addImageOverlay" (Printf.sprintf {|{...}|} ...)
After: Leaflet_map.add_image_overlay map ~url ~bounds ~opacity:0.7 ()

Before: Scanf.sscanf json {|{"lat":%f,"lng":%f}|} (fun a b -> ...)
After: on_click:(fun pt -> ... pt.lat ... pt.lng ...)

The GeoTessera embedding tiles have pixel grids in UTM projection, but the
notebook was overlaying them as if they were on a regular lat/lng grid. This
caused ~3-6% east-west distortion at mid-latitudes (e.g. ~440m at 52N).

- Add pure-OCaml UTM projection module (utm.ml) with WGS84 ellipsoid
forward/inverse transforms
- Add reproject_tile function that resamples each tile from its native UTM
grid onto a regular WGS84 grid using nearest-neighbor interpolation
- Mosaic now reprojects all tiles before assembly, matching the Python
reference implementation (ucam-eo/tessera-interactive-map) which uses
rasterio.warp.reproject for the same purpose
- Return computed WGS84 bounds from fetch_mosaic_sync instead of requiring
callers to hardcode snap ± 0.05
- Fix jtw relativize_or_fallback for dune exec paths (dynamic_cmis.json
generation was silently skipped for locally-built packages)
- Consolidate deploy-site.sh as thin wrapper around build-site.sh

lwt 6.1.1 fails to compile on oxcaml 5.2.0+ox due to type changes
in Unix.recv/send. The ox repo provides lwt.6.0.0+ox which works.
Adding an upper bound ensures the solver picks the right version.

When multiple findlib packages share a single directory (like
compiler-libs.common, .bytecomp, .optcomp, .toplevel), the old
directory-wide preload check would see all CMIs from all packages
and incorrectly report "partially loaded" — then try to reload
archives that were already linked, crashing with "file already exists".

Fix: use ocamlobjinfo at build time to extract per-CMA unit lists,
embed them in dynamic_cmis.json, and check only the relevant archive's
units at runtime before deciding whether to load its .cma.js.

Instead of requiring every .mld file to specify @x-ocaml.universe and

once in dune-workspace (--config x-ocaml.universe=/_opam). The shell
emits <meta> tags from config values, and per-page @x-ocaml tags can
still override them.

- gen_rules.ml: pass --config to odoc html-generate for @site build
- odoc_jon_shell.ml: emit <meta> tags from x-ocaml.* config values
