* ui: rationalise diagram block styling and pre transforms shared by mermaid and svg
* ui: live render streaming svg blocks
* ui: also render svg authored in xml code fences
* ui: refactor svg block rendering, address review from allozaur
- Move the svg size ceiling and DOMPurify config out of sanitize-svg.ts into /constants.
- Rename the svg-diagram class to svg-block so the name no longer implies diagrams only.
- Replace the svg, xml and svg tag magic strings in the markdown pipeline with shared constants.
- Promote the data-svg-rendered marker and its sibling data attributes to constants.
* ui: render svg blocks in a shadow root for animation and live zoom
Mount each sanitized svg inside an open shadow root so author <style> and
keyframe or smil animations run while staying scoped to the host element.
Relax the sanitizer to forbid only foreignObject and script, which lets
animation, href and external resource refs through for wider compatibility.
Render the inline block and the zoom dialog from the same reactive source,
so a streaming svg keeps drawing live inside the open zoom popup.

vulkan: support non-contig unary/glu ops (#24215)
* vulkan: support non-contig unary/glu ops
Change unary/glu ops to pass in all strides and use fastdiv for the index
calculation. Put all unary ops in one file, similar to glu, to share the
code. codex went ahead and added expm1 without me asking, but I had to
make it do a real precision analysis rather than just making stuff up.
unary.comp initially couldn't use generic_unary_head because there wasn't
space for xielu's additional constants. Fixing this required packing the
fastdiv 'L' values.

Swap the precedence so the WebUI per-request value is checked

UI/jpeg exif orientation (#24196)
* ui: bake jpeg exif orientation into uploaded images
stb_image in mtmd ignores exif metadata, so rotated smartphone photos
reach the model with raw pixel orientation. The webui now reads the
exif orientation tag at send time and feeds it into the existing
capImageDataURLSize canvas pass: the browser applies the rotation when
decoding, so capped images come out upright for free, and images under
the cap threshold get a single plain redraw when orientation > 1.
At most one re-encode ever happens per image. Upright jpegs with
capping disabled pass through untouched, bit perfect.
Adds jpeg-orientation.ts with a minimal exif parser working on a
bounded base64 prefix (both endianness, returns 1 on any malformed
input) and unit tests against handcrafted jpeg byte streams.
* ui: move jpeg exif constants into lib/constants
* ui: add browser test for jpeg orientation and capping
Covers capImageDataURLSize end to end in chromium with real Pillow
generated jpeg fixtures across exif orientations 1/3/5/6/8: upright
quadrant colors checked pixel-wise, expected dimensions with and
without capping, no orientation tag left in the output, and strict
passthrough when nothing needs rewriting.

speculative : fix "ngram-map-k4v" name in logging (#24253)
This is a non-functional change.
When using `--spec-type ngram-map-k4v`, the log messages at startup and
runtime say `ngram-map-k`. Added logic in the in the constructor of
`common_speculative_impl_ngram_map_k` to pass the correct
`COMMON_SPECULATIVE_TYPE_NGRAM_MAP_K4V` when `config.key_only` is
`false`.
After this change, the log messages use the correct name.
Expose a run_javascript tool to the model, executed entirely in the
browser through the existing agentic loop. Code runs in a Web Worker
inside a sandboxed iframe with an opaque origin, isolated from the
WebUI and its API. Console output, errors and the return value are
fed back as the tool result. The parent enforces a hard timeout by
removing the iframe, which terminates the worker.
Disabled by default, toggle in Settings > Developer.
* ui: address review feedback from allozaur
Use the JsonSchemaType enum for the tool definition parameter types
instead of raw string literals, extending it with STRING and NUMBER.
Move the worker shim and the iframe harness html into their own files
so the service no longer carries inline source blobs.
Replace the remaining magic strings with constants: SANDBOX_EMPTY_OUTPUT
and SANDBOX_TRUNCATION_NOTICE, and reuse NEWLINE_SEPARATOR for joins.
* ui: move sandbox worker shim to a raw imported file
Replace the inline worker template string with a real sandbox-worker.js
imported as raw text, and build the iframe harness from it in
sandbox-harness.ts. The raw worker ships as a string, not a module, so
it is excluded from eslint and the typecheck program.

ggml : add GGML_OP_COL2IM_1D (#24206)
* cpu: add GGML_OP_COL2IM_1D
Add the overlap-add (scatter-add) step of a 1D transposed convolution.
A ConvTranspose1d factorizes as a GEMM followed by col2im: a weight
pre-permuted to [IC, K*OC] is contracted against the [IC, T_in] input
with mul_mat to produce a column matrix [K*OC, T_in], and col2im_1d
scatters those columns back into the [T_out, OC] signal, with
T_out = (T_in - 1)*s0 + K - 2*p0.
Keeping the contraction as a plain mul_mat leaves the heavy work on the
optimized (and quantizable) matmul kernels, so col2im_1d only does the
cheap overlap-add.
CPU uses a gather formulation parallelized over output channels,
supporting F32, F16 and BF16 with an F32 accumulator.
* tests: add backend coverage for GGML_OP_COL2IM_1D
Add test_col2im_1d next to the conv_transpose_1d cases, covering F32,
F16 and BF16 across eight geometries: the canonical kernel = 2*stride
DAC upsampling shape, overlap, no overlap, cropping (p0 = 1 and
p0 = stride/2), kernel < stride with zeroed gaps, kernel not a
multiple of stride, and a single column unfold.
Perf mode gets three real vocoder stage shapes reporting memory
bandwidth. max_nmse_err relaxes to 5e-4 for F16 and BF16.
* cpu: harden GGML_OP_COL2IM_1D
ggml_col2im_1d validates s0, oc, p0 and input contiguity at graph
build time, before the oc division, protecting every backend at once.
The kernel asserts the contiguity its flat indexing assumes and its
doc states the full output length including the crop term.
The kernel parallelizes over the time axis: the split stays balanced
down to OC = 1, where the previous channel split was single threaded.
Values are bit identical on the three real vocoder chains, two out of
three improve.
* tests: extend the GGML_OP_COL2IM_1D grid
The eval grid grows to eleven geometries: OC = 1 (mono output stage),
K = 1 with stride > 1 (sparse scatter, every gap position zeroed) and
a crop down to T_out = 2 where all the gather bounds act at once.
* tests: add col2im_1d equivalence test
tests/test-col2im-1d.cpp proves mul_mat + col2im_1d matches the
native ggml_conv_transpose_1d on the CPU backend, F32 bit exact, F16
and BF16 through casts of the column matrix. test-backend-ops cannot
cover this for a CPU only op since the CPU backend is its own
reference there.
* rpc: bump protocol patch version for GGML_OP_COL2IM_1D
GGML_OP_COUNT goes from 96 to 97 with the new op, which trips the
static_assert in ggml-rpc.h. Bump RPC_PROTO_PATCH_VERSION since the
op is appended and no existing op code shifts.

* common : relax sampler name matching
Currently, in some cases, the alternative names for samplers (like
`top-k` and `min-p` instead of the canonical `top_k` and `min_p`) are
not always recognized by the `common_sampler_types_from_names` function
in `common/sampling.cpp`.
This PR changes the signature of this function to remove the `bool
allow_alt_names` flag, and removes all occurences of the flag from call
sites. Therefore, the function will now always match all known names.
I also changed the logic of the function to unconditionally check the
provided sampler names against both the canonical and alternative names,
and to be case-insensitive.
This fixes an issue I was seeing wherein samplers specified in the
`llama-server` UI were not recognized as valid when the alternative
names were used.
