- Text: kasra/fatha/damma/shadda/sukun/hamza-above and «هی» ezafe removed from every user-visible string (comments untouched); tanwin kept. Stale copy fixed (question packs are no longer sold), awkward onboarding sentences rewritten, سؤال → سوال. plainPersian() in MathText cleans the live tutor stream.
- Home: the mascot + speech bubble header is gone; the selected companion hops beside the current island and sits at every third bend (CSS transform animations only).
- Checkout: order summary, payment-method rows with Zarinpal/Bazaar icons and radio, amount on the pay button, lock trust line, darker overlay. paymentMethods in config.js per channel (web: zarinpal, app: zarinpal+bazaar by default).
- Profile: «ورود با حساب دیگر» removed (it was logout); new «حساب کاربری» sheet shows phone/ID and holds «حذف حساب کاربری»; logout is a red row. Delete sheet tells Bazaar subscribers to cancel renewal in Bazaar.

Measured by rendering every question, option and several tutor answers in
Chrome and comparing the on-screen x of each number (2026-09-29):
- A list inside a sentence ('از −۳ به −۲، −۱، ۰ میرسیم', 'الگویِ ۲، ۵، ۸')
was locked as one left-to-right run, so all 482 read backwards. '،' and
'؛' outside brackets now split the run; sets and coordinates in brackets
stay one run. Locked runs are isolates (isolate-override), otherwise the
comma between two of them was still pulled left-to-right.
- Without MathText 704 of 931 minus signs and 602 of 983 expressions were
misplaced; lesson and island titles, the lesson intro, unit blurb,
notification bodies and ticket messages now go through it.
- The chat box takes its direction from each line's first letter, so a
line of pure math stays left-to-right while typing. A line that starts
in Persian can still show its math reordered inside the box; a textarea
cannot isolate part of its text. The sent message renders correctly.
Four expressions with Persian words inside them ('f(x) = (ریشه دوم x) + ۵۰')
remain ambiguous.

- Every screen but home is its own chunk and preloads when the browser is
idle; React and motion get their own long-cached chunks. The app entry
goes from 505 kB (160 kB gzip) to 85 kB (27 kB gzip).
- Quiz prompts, options and lesson examples go through MathText, so
'10 + 3 - 7 - 2' reads from the left; an unpaired bracket at the edge of
a math run stays with the Persian sentence.
- Support lists tickets from GET /support/tickets instead of this
browser's localStorage; a ticket's messages load when it is opened.
- '·' next to a Persian zero read as another digit ('فصلِ ۱ · ۰' looked
like ۱۰۰); a thin bar separates them now. Notification bodies show
Persian digits.
- A root or vertex the model already marked with coordinates is no longer
labelled a second time on top of it.

- src/diagram: plane (constructed points, graphs with computed roots, vertex,
extrema, tangent, asymptotes, piecewise limits, regions, rotations and
reflections, line from ax + by = c), number line with intervals and stacked
fractions, solids with hidden edges, bar/line/pie charts, sign tables, Venn,
arrow mappings, probability trees, fraction bars and mixed numbers, grids,
groups, clock. Pure-math text is bidi-overridden: Persian digits used to turn
3 × 4 = 12 into 12 = 4 × 3 even with dir=ltr.
- MathText locks math runs inside Persian sentences in chat bubbles and figure
captions, so -1 no longer shows as 1-.
- Family screen: a student sees only the invite-code form; the parent form is
behind a link.
- Dev-only diagram gallery at ?gallery (not in the production build).
