The encode/decode is implemented in a WebAssembly module built from a
small C wrapper around libavif. Bundled libraries (statically linked,
compiled with the WASI SDK):
* libavif v1.4.1 (container + codec glue)
* libaom v3.14.1 (AV1 encoder + decoder)
* dav1d 1.5.3 (AV1 decoder)
* libyuv (Chromium pin) for color conversion
* parson for JSON message passing across the wasm boundary
HDR handling on the encoder:
* SDR images are written as BT.709 / sRGB / BT.601 (8-bit).
* 10-bit and up are written as BT.2020 primaries with PQ (SMPTE
ST 2084) transfer and BT.2020-NCL matrix coefficients, signalled
via CICP.
* Adobe-style SDR+gainmap inputs (e.g. Lightroom HDR exports) are
baked into a single true-HDR image in BT.2020/PQ at 10-bit, with
the CLLI (Content Light Level Information) box carried through so
HDR-capable clients can tone-map correctly.
Limitations:
* Animated input (animated WebP/GIF) is collapsed to its first frame
when re-encoded as AVIF; animated AVIF output is not yet supported.

With renderSegments only a subset of pages is rendered, so the resulting
hugo_stats.json would no longer contain elements from the excluded pages,
causing tools like Tailwind to strip classes that are actually in use.
Fixes#14939
Treat type and code as highlighting options in both transform.Highlight
and transform.HighlightCodeBlock. The type option overrides the language
and code overrides the code, so the two functions now share the same
options handling.
transform.Highlight's LANG argument is now optional:
transform.Highlight CODE [LANG] [OPTIONS]

When a module provides a config key whose value is a slice (e.g.
cascade or permalinks), and the site config declares the same key as a
map with only a merge strategy marker (_merge = 'deep'), the types do
not match and Params.merge silently dropped the module's value, leaving
the site with no effective cascade or permalink config from the module.
Fix Params.merge so that when the destination value is an empty Params
(IsZero — only the _merge key is present) and the source value is a
non-Params type, the source value is used provided the user-declared
merge strategy is not 'none'. This honours the explicit _merge
directive regardless of the surrounding shallow-merge context.

A partial's rendered output (placeholder included) is cached by
partialCached across rebuilds, but BuildState.DeferredExecutions
is reset every stage. On a fast-render rebuild the cached string
replays the placeholder while doDefer is not called this build,
leaving executeDeferredTemplates to panic with "deferred execution
with id ... not found".
Mark the ctx inside IncludeCached's body execution and have Defer
return a clear error if it sees the flag. Catches transitive cases
(partialCached -> partial -> Defer) via ctx propagation. Defer in
baseof.html and in a plain partial is unaffected.

Node's ESM resolver does not consult NODE_PATH (unlike CJS require), so
an ESM postcss.config.js shipped by a Hugo theme fails when loaded from
the module cache: bare imports like `import x from "postcss-import"`
have no node_modules to walk up to.
Install a synchronous resolver hook (module.registerHooks) via
--import=data:... on every Node invocation. On ERR_MODULE_NOT_FOUND for
a bare specifier it resolves the package from each NODE_PATH entry via
createRequire().resolve(). No-op for relative, absolute, URL-scheme and
non-MODULE_NOT_FOUND failures. Synchronous hooks run on the main thread,
so no --allow-worker is needed under the Node permission model.

If a non-default-name file in the config folder parses to a map with a
single top-level key matching the file's basename, unwrap it. This lets
TOML/YAML express slice-typed roots (cascade, permalinks), which can't
have a headless top-level array, and also lets users copy-paste docs
examples that include the root container (e.g. params.yaml with a
top-level params: block).

A stale or removed resource used by js.Batch could panic while the esbuild import loader read its content during a rebuild. Return the read error through the loader so esbuild reports a normal build error and a later rebuild can recover when the file returns.
Closes#13737
Smartcrop can return a crop rectangle that is smaller than the requested dimensions after prescaling and rounding. Expand that rectangle within the source image bounds before applying Hugo's crop/fill pipeline, so smart crops keep the requested size without stretching the image.
Bump the smart crop cache version for crop/fill only.
