The bug reads as a language-picker bug — switch off Mandarin on a phone and
the writing starts scrolling left and right — but the picker only changes
how wide Petal's own chrome wants to be. Every pill says its thing twice,
历史 · History against Historique · History, and every pill is nowrap and
shrink-0. So the title row's width is a property of the langpack: 459px in
Chinese, 551px in French, 506px in Portuguese, against the 338px column a
390px phone gives it. That row lives in the editor pane, and a pane that is
overflow-y: auto has an overflow-x of auto too, whatever the stylesheet
says. The overflow had nowhere to go but the page of writing.
Chinese was already 120px over. French is simply where it stopped being
possible to ignore.
The pills now live in a strip that scrolls itself, with overscroll-behavior
so a swipe off the end doesn't turn into a page gesture. What that buys is
the thing worth keeping: every label stays bilingual at every width. The
first version of this fix dropped the English half on phones, which fixed
the geometry by taking away the half she is learning from — on the device
she writes on most.
A scrolled pill that has left the screen is indistinguishable from a pill
that isn't there, so each edge with more behind it fades, the same hint
.petal-toolbar gives with its clipped right edge, except this row can be
scrolled from either end and has to point the right way. ChromeStrip sets
data-edge from the scroll position and re-measures when the pills resize —
which is also what catches every label changing width at once when she
switches her pair.
The tone and export menus had to leave with them. A scroll container clips
its absolutely-positioned children, so both menus would have been trapped in
a 36px-tall box; they anchor against the viewport now.
Two smaller ones the same measurement turned up:
- The header overflowed the viewport itself below 360px — a real
page-level scroll, 40px of it at 320px, off 🌷 Jardim de palavras ·
Garden. Narrower padding on phones, and under 360px the wordmark
yields. Of everything in that row it is the one thing that can go: she
is already inside the app, and the blossom stays.
- The language picker wanted 307px inside a 280px drawer and spilled out
of it. It wraps now. That one was broken in Chinese too, at 291px.
Verified in a real browser rather than by arithmetic: 310px to 780px in 10px
steps, in all three packs, no page overflow and no editor-pane overflow at
any width. Edge fades flip correctly, the export menu opens unclipped with
the strip scrolled to its end, tsc clean, 195 frontend tests pass. Desktop
is untouched — one 40px header row, as before.

🌸 Petal
A self-hosted, privacy-first writing editor with warm bubbly design, auto-save, and
local-LLM grammar/ESL suggestions. See petal-spec.md for the full
design spec and BUILD_PLAN.md for build progress.
Stack
Go + chi backend · SQLite (modernc, pure Go) · React + Vite + Tiptap + Tailwind v4 frontend ·
local vLLM/Ollama for AI suggestions. Single-binary deployment (frontend embedded via go:embed).
Local development
Two processes during development:
# 1. Backend (serves /api on :8080)
go run ./cmd/server
# 2. Frontend dev server (HMR on :5173, proxies /api → :8080)
cd web && npm install && npm run dev
Open http://localhost:5173 while developing.
Production build (single binary)
cd web && npm run build # emits web/dist (embedded by the Go binary)
cd .. && go build -o petal ./cmd/server
./petal # serves UI + API on :8080
Configuration is via environment variables — copy .env.example to .env.
Deployment
docker compose up -d --build # petal + the two Piper read-aloud sidecars
Behind Traefik on the parodia.dev VPS; vLLM stays on millenia over headscale.
Full runbook — first deploy, the LLM link, backups and restore — in
deploy/README.md.
Status
Early build, multi-session. Auth (Authentik OIDC) is next; Copyleaks plagiarism is
still parked — see BUILD_PLAN.md.
