me.nech.pl/<KEY> resolves at build time to a post in one of its
languages, reusing PostArticle wholesale. generateStaticParams runs the
collision guard so a future slug can never silently shadow a route;
drafts mint nothing here in prod and the page re-checks.

Each language file may declare its own localized slug (the folder name
stays the canonical slug). A post's resolvable set: canonical folder slug
to the default language, localized slugs to their language. lib/keys.js
gathers the reserved root names (routes, legacy pages, public/ files,
hardcoded floor) and fails loudly on a colliding or twice-claimed key.

The 8x6nki / szm8ld share-id gates stay explicit. New coverage:
available-language reporting, requested-language fetch with the
untranslated banner flag, prod filtering still keyed on NODE_ENV, and
the language-nav banner/switcher data. The both-languages path runs on
a synthetic _fixture-bilingual post (removed after the suite) — real
posts are single-language by design.

Sveltia/Decap i18n structures (single_file, multiple_files,
multiple_folders) can neither produce <slug>/<locale>.md nor carry a
shared non-localized meta file, so the folder is exposed as three
monolingual entry collections pinned to their file by the path
template: blog -> <slug>/meta.md, blog-fr -> <slug>/fr.md, blog-en ->
<slug>/en.md. app_id and PKCE untouched.

lib/blog.js now reads content/blog/<slug>/ (meta.md + fr.md/en.md):
listing shows the requested language with fallback to the first
available one, getBlogPost(slug, lang) reports untranslated posts via
an untranslated field, and the draft/share accessors keep parsing
<slug>-<token> from meta.md. Draft filtering stays keyed on the shared
draftsVisible() rule, now exported from lib/content.

/blog/[slug] renders the default language with an FR/EN switch when a
post exists in both; a new /blog/[slug]/[lang] route serves the other
language (static params only mint languages with content). A missing
language renders an honest banner linking to the one that exists.
yarn post scaffolds the folder shape. Flat collections are untouched.

Each post is now a folder: meta.md (shared metadata) + one file per
language (fr.md / en.md) carrying the localized title and body.
Language files go where the existing prose actually is: hello-world
and hello-world-again are French, next is English. Share tokens
(8x6nki, szm8ld) move to meta.md so the unlisted /blog/d/ URLs keep
working; the post image stays in public/images (no move needed).

docs: article contract gains embeds — build-time code from git.nech.pl/github/raw, directive islands

/admin serves Sveltia CMS from a pinned jsdelivr bundle (0.229.0) with a
cms-config-url link to ./config.yml; HTML comment documents the Decap
fallback (same config, swap the script). Backend points at git.nech.pl
with base_url + api_root for the self-hosted instance, PKCE app_id
filled in, implicit grant noted as fallback. Blog collection fields
match the existing frontmatter; media folder public/images/blog with
public_path /images/blog. scripts/new-share-token.mjs prints a random
6-char token for the unlisted draft links.

Drafts with a well-formed `share` token in frontmatter ship to prod at
/blog/d/<slug>-<token>: robots noindex/nofollow, no OpenGraph, token
re-checked at render so a guessed slug renders nothing, tokenless drafts
get no unlisted path. Article markup factored into a shared PostArticle;
the public listing and /blog/[slug] keep filtering drafts out.

Also: static export requires at least one prerendered variant per dynamic
route, and prod currently has zero published posts — emit a 404 sentinel
param so the export still ships (build broke at HEAD for this reason).

Same grammar as Clarté TDAH (clarte kit: ProgressHeader, QuestionCard,
OptionPills, useDigitKeys), linear 25-item flow: consent-gated home with
optional gender, intro, auto-advancing questions, recap with jump,
results with total band + percentiles vs autistic and non-autistic
norms, five interpretation caveats, copyable consult sentence, jspdf
report. FR at /tsa, EN at /asd, mirroring /tdah + /adhd.

25 items Likert 1-7 (verbatim Hull 2019 in EN, our translation in FR,
flagged non-validated), items 3/12/19/22/24 reversed, subscales
compensation/masking/assimilation. Percentiles via normal CDF on the
Hull 2020 gender-matched norms; Baker 2024 descriptor bands on the
total score. Storage contract catq:v1, same discipline as clarte:v1.
