dtourolle 10216355c1 Render the manual as one HTML page the application can carry
The manual existed only as docs/manual/README.md, which the forge renders
and nothing else does. An installed copy of the application, on a laptop
with no network or on a tablet, had no manual it could open.

`traces manual` renders the README to docs/manual/index.html with
pulldown-cmark (already in the tree as Slint's Markdown parser, so this
adds a dependency edge and no crate). The page is one file with an inline
stylesheet that follows the system's light or dark preference, a
contents list of every section and subsection, and the pictures by their
relative media/ paths. Each heading carries the id the forge gives it, so
README.md#rating-and-flagging and index.html#rating-and-flagging are the
same link. A picture alone in its paragraph becomes a figure whose alt
text is shown as the caption, and every picture reserves its 16:11 box
before it loads, so a jump into the middle of the page lands where it
aimed rather than a screenful above. Links to design documents, which the
installed page has no copy of, point at the forge.

The page is committed rather than rendered at build time, as the gesture
book is: it is user-facing text reviewed in the diff, and the three
packagers then only copy it. `traces manual-check` fails in CI when the
committed page is not the render of the README, and the pre-commit hook
regenerates it when the README is staged.

# *same* `wgpu::Device` Slint renders with, and Slint will only hand out a
# device of the version it was compiled against. Slint 1.17 offers
# `unstable-wgpu-28` and `unstable-wgpu-29` and nothing older, so 29 it is —
# pinned to the same `29.0.4` floor Slint itself requires, because two
# semver-compatible-but-different wgpu crates in one tree are two *types*, and
# the device would not typecheck across them.

# Lens correction profiles. A pure-Rust port of Lensfun rather than a binding

#
# The database ships *inside* the crate — 56 XML files, gzipped at build time
# and decompressed on first lookup. That matters beyond convenience: Android
# gives us no filesystem path (ARCH §6.9), so a database loaded from a
# system directory would have nowhere to live there.
#
# Licence: LGPL-3.0-or-later, which upgrades cleanly into our GPLv3 (D8).
# The upstream Lensfun *database* is CC-BY-SA and is redistributed by the
# crate; attribution belongs in the about screen.
#
# Caveat worth remembering: this is a third-party port at 0.7.0, not upstream
# Lensfun. Verified working against the bundled database (interpolation
# between calibration points, and an unknown lens returning empty rather than
# panicking), but the pipeline talks to it through its own profile types so
# swapping it out is not a pipeline change.

# Neural inference for semantic segmentation (S15 arm B, D14).
#
# D13 framed this as a choice between `ort` (fast, best operator coverage, and
# a C++ dependency to cross-compile under the NDK) and a pure-Rust runtime
# (policy-compliant, unproven coverage). That framing turned out to be a false
# choice: `ort` 2.0's `alternative-backend` feature *disables the linking
# entirely* and lets a different engine supply the `OrtApi`, and `ort-tract` —
# same authors, MIT/Apache — supplies it from `tract`, which is pure Rust.
#
# So we get `ort`'s API with no C at all. `download-binaries` and `tls-native`
# are off with `default-features = false`, which is the point: nothing is
# fetched at build time and nothing is linked, so the Android cross-compile
# sees an ordinary Rust dependency graph. That is the same reasoning as rustls
# over aws-lc-rs and bundled SQLite, applied to inference — D13's largest
# tolerated exception turns out not to be needed.
#
# The trade is real and belongs on the record: tract is slower than the C++
# runtime and covers fewer operators. Both were measured rather than assumed
# before this landed — yolo26n-seg loads with **zero unsupported operators**
# and runs 640x640 in ~470 ms on the reference desktop's CPU. That is fine for
# a once-per-image precompute off the frame path (ARCH §6.1) and would not be
# fine for anything per-frame, which is a constraint on what may be built on
# top rather than on this choice.

#
# This deliberately reverses an earlier choice. Dependencies used to be built
# at `opt-level = 2` here, because wgpu and image decoding are slow without it.
# That is still true, and it is the price: a debug run of the app, and the
# decode- and GPU-heavy tests, are slower than they were. What it buys is that
# nothing has to be optimised before it can be compiled — which is the cost
# paid on every edit, by every worktree, rather than only when something is
# actually run.
