bdeshi 2b0387e997 serve robots.txt and sitemap.xml
Two exact paths a crawler asks for by name, so they are mux entries rather than
resolver cases — no bundle can collide, since a key always sits under a section.

robots.txt at the site root is served verbatim, because a site that ships one has
said something deliberate; otherwise the engine emits the minimum that is true and
points at the sitemap. The sitemap lists every bundle in every language it exists
in, since each variant is separately reachable, with lastmod only where a bundle
has a date. Every URL comes from content.URL like every other path the engine
emits, so a sitemap cannot disagree with what is actually served.

Both need a declared base. Without one the sitemap answers 404 rather than listing
paths no crawler can resolve, and robots omits the Sitemap line rather than
writing a relative one.

write() was setting text/html for every caller, and headers only go out with the
first byte — so a handler setting its own type would have had it silently replaced,
which is how a sitemap gets served as a web page. It now splits into write and
writeAs, and the tests assert the content types rather than only the bodies.

bdeshi d67cfd186f include another file from the bundle, one level deep
{{< include file="notes.md" >}} renders a file from the bundle as Markdown in
place. The included file is converted by the same goldmark instance that is
rendering the page — handed to the transformer in Extend — so its configuration
can never drift from the page's.

Three properties, each tested:

A name containing ".." is refused. os.Root would stop a path leaving the site
root, but path.Join collapses ".." long before the filesystem sees it, so without
this an include could read a template or a stray dotfile from the site root and
publish it. Verified the test fails without the guard: it took three levels of
".." from content/pages/d to reach the root, and the first version of the test
used two, so it passed either way and proved nothing.

An include inside an included file renders nothing and logs. The nested parse is
marked, so one level is all there is and a file including itself is a log line
rather than a stack overflow (ADR-0038, ADR-0029).

A gallery inside an included file still resolves, because the nested parse carries
the same Origin.

The node gained `content` for output a feature produced itself, plus `isContent`
so a failed include renders nothing instead of falling through to a fragment
lookup and complaining about a template that was never meant to exist.

bdeshi 61ae5c9c14 add the gallery shortcode and the seam it needed
A feature now learns which bundle is rendering: render.Bundle puts an Origin —
the bundle's directory plus the rooted fs.FS — on the parse context, and
render.OriginFrom reads it back. Available while parsing, not while rendering,
which decides where a feature does its filesystem work: goldmark hands the
context to a block parser and not to a node renderer, so gallery gathers its
filenames at parse time and carries them on the node.

Reads stay inside the site root because Origin passes the fs.FS rather than a
path to join (ADR-0031).

Fragment{Args, Items} lands with it (ADR-0037), so figure's template now reads
.Args.src. Authored arguments and engine-gathered items stay in separate fields:
a src argument beside a src the engine found would otherwise silently pick one.

A gallery is pictures beside the bundle, in filename order, skipping
subdirectories and anything a browser cannot show. Filename order is what makes
the sparse numeric-prefix convention work without numbers in URLs (ADR-0016).

New latent row: the reference theme's images carry no width/height and a
gallery's carry no alt, which is below the output floor conventions.md states.
Nothing can supply either yet — dimensions need the image read, and a filename is
not alt text. Queue 13 computes dimensions and brings structured items with it.

bdeshi 820720de08 add shortcodes as the first internal/ext feature
A call is `{{< name key="value" >}}` alone on a line, parsed by a goldmark block
parser into an AST node and rendered by executing a theme template of that name
(ADR-0036). `figure` ships; `include` and `gallery` need the including bundle's
directory, which the parser does not carry yet, so they wait.

The layering did the design work here. internal/render may not import
internal/ext, so render.New takes a callback that receives a Partial and returns
Markdown extensions, and cmd/khosra/wire.go holds the only list of enabled
features. Empty that list and the engine still builds and serves — which is the
property extensions.md says the contract should have.

Raw HTML stays disabled. An author's text reaches a page only as arguments that
html/template escapes in context, which the real binary shows: a hostile alt
becomes &lt;script&gt; and src="javascript:…" becomes #ZgotmplZ. Getting
contextual escaping from the standard library rather than writing it is the whole
reason a fragment renders this instead of the feature.

parseSet became variadic so the fragment set reuses it rather than growing a
second copy of the overlay logic; `Partial` takes map[string]string after the
advisory correctly flagged `any` as generality nothing had asked for.
