The pairwise vertical path (Chinese, Korean and plain text) grew ruby
bases without first computing overhang rooms, so a long Pinyin reading
always spread its base. Horizontal text, and vertical Japanese, let the
reading hang over an adjacent kana, comma, full stop or middle dot.
Run set_ruby_overhang_rooms before grow_ruby_bases on that path too. It
uses ruby_overhang_room, the rule horizontal applies to every language,
so Han neighbours still take no overhang and ruby-overhang none keeps
the old growth. A comment at the early return notes that warichu never
splits there: only Japanese renders warichu.

The mark box used the mark's em box (half the base size, square), while
painting placed the shaped mark by its tight rect: advance wide, ascent
plus descent tall. Text bounds, selection and export therefore disagreed
with the canvas; over marks could paint above the bounds.
Shape each span's mark once in HorizontalEmphasisMark and place that
measured box for paint, text bounds and position data alike. Position
data keeps an em box, now centred on the painted mark, because SVG
export draws the mark at a font size equal to the box width.
Tests that built synthetic placements now pass the mark ink explicitly;
their assertions are unchanged. Vertical marks had no mismatch: paint
and position data centre on the same point.

The text options started with Japanese only. Chinese and Korean reused
its controls and helpers, which kept Japanese names, and some rules got
a copy per language.
- Rename text-japanese-layout to text-cjk-controls: the controls every
language panel shares. The Japanese panel and its own controls move to
text-language-layout, next to the Chinese and Korean ones.
- Share one option row, one writing mode row (languages add their radio
groups to it), and one emphasis and clearance select per language.
- Rename the selection, plugin and HTML style helpers from japanese to
cjk, `schema:jl-enum` to `schema:cjk-enum`, and the stored writing
mode helpers to `stored-writing-mode` and `stored-vertical?`, apart
from the rendered ones in writing-mode.
- Build the language label and dropdown from one table of languages,
and rename the profile-* translation keys to language-*.
- Decide the attrs each language renders from one table per level
(root, paragraph, span).
- Serialize korean-wrap through the CJK enum table and RawKoreanWrap.
- Compare the CJK option attrs in a loop in the text menu.

Several CJK passes had a copy per writing direction. Merge them without
changing their results:
- allocate_bounded_expansion and bounded_expansion divide justify and
distribute slack for both axes. Each axis still collects its own gaps;
the horizontal one checks no-break controls over the source range and
the vertical one at cell edges, as before.
- PolicyBoundaries holds the break and emergency rules at each grapheme
of a paragraph. The horizontal overlong-word and atomic-overflow passes
and the vertical pairwise column planner read it. relax_overlong_words
moves next to retain_atomic_overflow and shares annotation_ranges.
- TextLayoutPolicy::pair_spacing_em gives the compression and script gap
that both axes apply with their own caps.
- cjk_chars keeps the Han, kana, hangul and punctuation ranges. Ranges
that differ on purpose stay separate there, with a note on why.
- OverhangClaims tracks the ruby overhang an earlier reading takes.
- horizontal_zhuyin_glyphs places Zhuyin for position data and painting.
- paint_horizontal_annotations paints warichu, emphasis and ruby; the
emoji overlay keeps its place between the marks and the ruby.

TextLayoutPolicy had nine flat variants that mixed language, Chinese
region and Korean wrap. It is now Plain, Japanese, Chinese(ChineseRegion)
or Korean(KoreanWrap), and the layout code asks it named questions
(uses_jlreq, plans_breaks, keeps_overlong_units, reopens_overlong_words,
bounded_justify, needs_joiner, normalizes_western_spaces,
uses_clreq_positions, ...) instead of comparing variants.
Paragraph parses its language once, when the language or the Korean wrap
changes, and copies the policy to its spans. Span code no longer builds a
policy from the tag with a dummy Korean wrap, and the emphasis and
underline positions take the policy instead of a Chinese flag.
A LanguageTag parser now serves both the layout policy and the CJK font
choice. It also accepts '_' as a separator, as the font choice did, so
a tag such as "ja_JP" now selects the Japanese policy.
The korean-wrap byte decodes through a new exported RawKoreanWrap enum
(Syllable=0, SpacesOnly=1, KeepWords=2) with the same byte values.

The CJK layout code kept names from when it only handled Japanese.
Chinese regional presets, Pinyin, Zhuyin and Korean now share it, so
rename the modules and helpers to say what they do:
- kinsoku.rs becomes line_breaks.rs: the layout-text rewrite with
OffsetMap and the inserted break markers. The kinsoku predicates move
to jlreq.rs (was japanese.rs); JapaneseClass becomes JlreqClass.
- is_japanese_text_char becomes is_cjk_text_char.
- text_japanese.rs splits into text_attrs.rs (span attribute enums),
text_ruby.rs (ruby pieces and overhang), text_warichu.rs and
text_allocation.rs (capped_equal_allocations, shared by both axes).
- wasm/text/japanese_layout.rs becomes layout_attrs.rs.
- RubySide becomes AnnotationSide; RawTextSpan.ruby_side becomes
ruby_flags, since the byte packs the side and the Zhuyin bit.
- horizontal_aki_sheds becomes the horizontal_pair_spacing dispatcher
with a jlreq_aki_sheds branch; the plan field sheds is pair_spacing.
- The policy_* helpers become pairwise_* and the Japanese ones jlreq_*.
- The oikomi policy parameter is adjustment and minimum_oikomi_extent is
min_squeezed_extent.
Exported functions, Raw* enums and byte layouts stay unchanged.

The CJK text options were behind per-language "Enable layout" toggles in
the file menu and the settings, each with its own sidebar section. A text
now has one language, picked in a single Language panel, and the options
of that language show below it.
- Rename the `vertical-text-layout` flag and feature to `cjk-support`.
- Remove the per-file and per-profile layout toggles, the file options
that stored them and the `:set-text-layout` change.
- Add the Language panel: a grouped dropdown of Japanese, Korean and the
regional Chinese variants, a row to change the language and a button to
remove it, "Mixed" when the selected texts differ. Picking a language
writes it to every paragraph of the texts.
- Render the CJK attrs only under the language that uses them, so a text
without language is horizontal and plain. The stored content keeps
every attr.
- Remember the last picked language for the next new texts.
- Add File > Language: the language of the texts without one of their
own, applied at render time and laid out again when it changes.
- Add the profile text language in Settings > Options: new files start
with it as their file language.
- Extract the grouped dropdown of the board size presets into a shared
component used by the presets and the Language panel.
- Name the Japanese readings furigana, drop the redundant prefixes of
the furigana and pinyin options, move Distribute below the writing
mode row and show only the position sides of the writing mode.

Finding the line-end squeeze laid out the whole paragraph again for every
line, so the cost grew with the square of the length and typing in a
long Japanese text lagged.
Lines break greedily, so a line depends only on the text from its start.
Lay out a window from the line start that holds the line and the next
one, doubling it when needed, keep it while no squeeze changes the sheds,
and lay out the full paragraph once at the end. A test checks the sheds
match a full relayout.

Readings paint above the line box, outside the glyph metrics. The text
bounds joined the emphasis marks only, so an auto-width text with ruby

The narrow-box overflow plan, which lets an indivisible unit overflow a

An `all` composite gave up below half width, so "2027" in a font with
proportional digits (about 0.45) stayed sideways, while `digits` combined
the same run down to 1 / length.
A Western run no longer than a `digits` composite now squeezes as far as
one. Upright CJK and longer runs keep the half-width limit, since a
deeper squeeze makes full-width glyphs illegible.

When an item overflowed a column, column_break moved the characters that
may not start a column into the next one, and only checked that they fit
there with the overflowing item. The characters after it may not start a
column either, so a run longer than a column was pushed out again at
every column: "ださい。ー、ャュョッ。" in a five-character box left
"ださ", "い", "。" and "ー" alone in four columns.
Measure the whole unit that moves, up to the next allowed break, and keep
the natural break when that unit is longer than a column.

Font fetches are shared per URL, so a text that asks for a face already
being fetched gets no fetch callback. process-pending only relaid out
text after its own callbacks, so such a text kept its fallback-font

text stayed wrong until another change.

Zhuyin, Pinyin and emphasis marks over horizontal text were placed
against an em box bottom-aligned to Skia's tight glyph rect, which spans
the hhea ascent and descent. In CJK faces the descent reaches past the
em box, so Zhuyin columns sat about 0.17 em below their base, and over
annotations relied on a hand-tuned clearance.
Place them against the ideographic em box (OS/2 typo metrics) of the
font that shaped each base, centred on the line baseline, the same
metrics vertical text uses for upright glyphs.

Skia keys a line's style runs by UTF-8 byte offset, while line indices
are UTF-16. Decoration segments searched those runs with UTF-16 offsets,
so with CJK text every underline or strike on a line took the paint of
the first run, and a decorated span wrapped onto a new line lost its bar.
Look up each segment's run by the span's UTF-8 style anchor, falling
back to the line's first run for a span continued from an earlier line.

Each ruby reading attached its lowest ink to the base, which suits kana
but not Latin letters: the descender of "y" lifted "yǒu" above "liáo"
over 友聊, and under ruby moved with ascenders and tone marks.
Western letters in a reading now take the font's descent (over) or cap
height (under) instead of their ink, so Pinyin and romaji readings share
one baseline and descenders stay clear of the base. Upright glyphs keep
the ink edge.

The fifth alignment button made the first row of the text options 36px
wider than the sidebar grid: the options button fell outside it and the
panel scrolled sideways.
Distributed alignment is an East Asian convention (均等割り付け, 分散对齐,
배분 정렬), so it moves out of the alignment group into a switch of the
Japanese, Chinese and Korean layout sections, shown when the text's
language matches. Turning it off aligns the text to the start. The label
shortens to fit beside the switch.

SkParagraph moves each line right by half the letter-spacing of its first
character. That centres span tracking, but the spacing added to single
characters (distribution and justification gaps, squeezing, compression
and ruby room) must only open the gap after them. A distributed label of
two characters started half a gap in and overflowed the box by as much:
"国家" in a 200px box drew 国 92px from the left edge.
Builders of horizontal text record how far each adjusted character's
letter-spacing departs from its span tracking, and `LayoutParagraph` takes
back half of that on each line, next to its baseline shifts: painting,
glyph and placeholder rects, line metrics, hit testing and text paths.
Span tracking keeps its half spacing before the line.

The paragraph language selects the CJK typesetting rules (line breaking,
punctuation spacing, the default emphasis position and localized glyphs),
but plugins could not read or set it. `lang` holds it as a BCP 47 tag, as
the HTML `lang` attribute does; `null` or `''` removes it.
On a text shape it applies to every paragraph and reports 'mixed' when
they differ. On a text range it applies to the whole paragraphs the range
touches: `update-text-range-attrs` now writes paragraph attrs such as the
language there instead of copying them into spans. The tag pattern moves
to `schema:text-language`, shared by the content schema and the plugin
validator.

Four fixes to how `digits` tate-chu-yoko composites lay out in vertical
text:
- A lone digit combines too, as CSS `digits <n>` combines runs of n or
fewer, so it stands upright instead of turning sideways. The renderer
(`split_digit_runs`) and the export path (`digit-combine-segments`)
share the rule.
- Composites centre on the OS/2 typographic metrics, like upright glyphs.
The hhea ascent of CJK faces exceeds the em, which set digits about
0.07em below the kanji beside them.
- Letter-spacing stays outside the composite, as in CSS. Counting the
trailing spacing in its width moved the digits left by half of it.
- The regional Chinese profiles no longer add the Han/Western gap around
a composite: it sets in one ideograph's cell, as JLREQ already does.

Styling a range splits spans at its ends, and nothing joined them back, so
a text kept invisible boundaries between spans with equal styles. Two CJK
features depend on those boundaries: tate-chu-yoko `all` combines per
span, so "2" + "027" rendered as two upright blocks, and a ruby reading or
warichu note over a range that crossed a hidden boundary was rejected.
`merge-equal-spans` joins neighbouring spans of a paragraph whose styles
match, counting a missing attr as its default value. Spans with a reading
or a warichu note are never joined: each one is its own group. Both places
that split spans use it: `update-text-range-attrs` (plugin API) and
`apply-attrs-to-paragraph` (WASM editor styling).

* ✨ Render email templates inside the mail job
The web process rendered each email to full subject and HTML body
before submitting it, so every queued job carried a huge params
payload. The queue now stores only the template id plus the raw
template data, and the new :send-templated-mail job renders and
sends the email inside the worker.
The old :sendmail job stays in place to drain jobs submitted in the
previous format; the quota notice and the REPL test mail keep using
it. All templated callers (auth, profile, feedback, invitations,
comments, Nitrate) submit recipes through eml/send-template.

stay ::eml/-namespaced and values stay plain data, and the single
templates set rejects unsendable mail both at submit and in the

organization invites and renewal notices failed without a retry.
Each registry entry now carries the JSON encoder and decoder of its
template schema: send-template encodes the data before submit and the
worker decodes it before rendering. The job schema keeps only the mail
envelope, as the template schemas own the typed data.
