Name the destination page in the continue link

"Continue to your account" says nothing about where the link goes. Use
the chosen page's own title instead — "Continue to Book a Lesson" — so
the visitor knows before clicking.

An untitled page keeps the generic wording rather than rendering
"Continue to ".

+## [1.2.3]
+
+### Changed
+- A **monthly group class is now billed its price once per month**, however many times the class meets in that month. Previously the monthly charge multiplied the price by the number of sessions in the month — a class priced at `40.00 CAD` meeting weekly was billed `160.00 CAD` on the 1st — which no studio could quote honestly on a class card. A monthly **private lesson** is unchanged: its price is a per-lesson fee and the month is still billed one fee per lesson, which is why it is quoted per lesson. Studios running a monthly group class should check the class price now reads as the monthly fee they intend to charge.
+
+### Added
+- Every price a student sees now says **when** it is due. Lesson types in the booking form read `50.00 CAD at booking`, and group-class cards read `120.00 CAD up front`, `40.00 CAD weekly` or `40.00 CAD monthly` — the offering's billing mode, in the student's words. A monthly **private lesson** is quoted per lesson (`50.00 CAD per lesson monthly`), since its monthly charge covers every lesson booked that month; a monthly group class is quoted as the monthly figure it is. A free offering still just reads **Free**.
+- The **Policies** admin page can now **show you what is actually in a version**. Every row in the versions table has a **View** button that opens that version's text below the table, rendered exactly as students see it at booking and signup, whether the version is the published one, an old archived one, or a draft nobody has seen yet. The text is editable straight from the viewer, and what happens when you save depends on the version: a draft is simply updated in place, while editing a **published or archived version saves your text as a new draft version** and leaves the original exactly as students accepted it. The new draft then opens in the viewer ready to publish. Nothing a student has agreed to is ever rewritten.
+- Booking a lesson and enrolling in a class now take a **second confirmation that the student agrees to pay**. Above the Confirm button the form restates the price with its cadence, spells out how it is collected ("Charged on the 1st of each month, for that month's lessons"), adds the studio's HST so the figure matches the total actually billed, and requires a tick on "I agree to pay 56.50 CAD at booking." before it will submit — separate from, and in addition to, the studio policies the student accepts above it. Reserving a time weekly quotes the per-lesson fee and the most it can add up to ("up to 12 lessons, 678.00 CAD in total"), since a week another student takes first is simply not booked. Free offerings have nothing to agree to and show no price block.
+
+### Fixed
+- Policies are **readable where students have to accept them**. A policy typed as plain paragraphs — the normal way to write one, with no HTML — was being dropped into the booking, enrolment, and signup forms unformatted, collapsing the whole document into a single squashed line with a horizontal scrollbar and words piling on top of each other. Policy text is now formatted the same way WordPress formats post content, so blank lines become real paragraphs, and the acceptance box is styled as a proper bounded reading panel: long policies scroll vertically instead of running off the side of the page, long pasted links wrap rather than forcing the page sideways, and the "I have read and agree" tick stays in view. Policies written with HTML are unaffected. The studio registration page was also missing the plugin's stylesheet entirely, which is why the problem was at its worst there.
+
+## [1.2.2]
+
+### Added
+- The **Lesson Booking** block gained three embedding options in its sidebar. **Lesson type** pins the block to a single private-lesson type — only the times bookable as that type are listed and it is the only thing bookable there, auto-selected on the registration form — so a page about one lesson type can carry its own calendar. **Show the lesson-type filter** turns the **Show Only** control on or off. **Sections** embeds just one half of the page: booking calendar only, or the student's upcoming lessons only, so the two can live on different pages. All three are available to the shortcode as `[us_booking lesson_type="…" show_filter="no" show="booking|upcoming"]`, and the block's editor preview follows the chosen sections.
+- The booking calendar now has a **Show Only** button beside the List/Week toggle that opens a lesson-type filter, so a student browsing open times can narrow them to the types they actually want. Because not every open time can be booked as every private-lesson type — some times are tied to a specific type, others only take types of a matching length — the filter shows just the times bookable as the ticked types, and re-anchors the week view on the earliest one so it never opens on an empty week. Picking one of those times narrows the **Lesson type** picker on the registration form to the same list, and when only one type is left it is chosen automatically with its questions loaded. The type list starts collapsed and can be tucked away again without losing the filter; the button shows how many types are ticked. Tick nothing (or use **Show all types**) to see every open time as before. The filter is hidden when the studio only offers one private-lesson type.
+- The **Group Classes** block can now be pinned to a single class, under **Classes shown → Class** in the block sidebar (shortcode: `[us_group_classes offering="…"]`). Pick a class and the block shows only that one, so it can be embedded on a page that describes the class. In this mode the class's own description is left out to avoid repeating the page copy — the card shows the schedule, instructor, price, enrolment deadline and the enrol/withdraw controls. Leaving it on **All classes** keeps the full browsable catalog with descriptions.
+- The **Student Registration** block can now send students onward to a page of your choosing once they finish registering. Its **After email confirmation** panel is now **After registration**: the page you pick there is where the link shown to a newly registered student points — the "Sign in to your account" link after they confirm their email, and a "Continue to your account" link for an invited student, who is signed in immediately. A new **Redirect automatically** option takes them straight there instead of showing the link. Registration errors are never skipped — a failed sign-up and an expired confirmation link still show their message on the page, as does the "check your email to confirm your address" step. The redirect needs a page to be chosen; with none set, students see the link (or, for invited students, just the confirmation) as before.
+
+## [1.2.1]
+
+### Fixed
+- Registration questions, offering titles/notes, and policy names longer than their storage limit are no longer silently discarded. Previously typing a fixed-size field past its maximum length reported success but saved nothing — the database quietly rejected the over-long value. These fields now cap the input in the form, and the API rejects an over-long value with a clear error.
+- Students can no longer reach the WordPress dashboard. A student who navigates to `wp-admin` is redirected to the site front end and the admin toolbar is hidden for them, so they only ever see the studio's booking pages. Anyone who runs the studio — administrators, studio admins, and instructors — keeps full `wp-admin` access.
+- The instructor picker on the **Add/Edit Offering** form no longer comes up empty for a solo studio owner. When the person running the studio teaches from a WordPress administrator account (the default single-account setup), they now appear in the instructor dropdown and can be assigned to a class.

The link names the chosen page (via `get_the_title()`) so the visitor knows where it goes; an untitled page falls back to "Continue to your account" rather than reading "Continue to ". Neither gets the WordPress-login-screen fallback — with no page chosen there is no link at all, since sending someone already signed in to the login screen is the same dead end with extra steps.

It fires only on those two finished states (`RegistrationPage::isRegistrationComplete()`), so the "check your email" step, a validation error, and an `expired` confirmation link are always shown rather than redirected past.

A **Show Only** button beside the view toggle opens a lesson-type filter that narrows the open times to those bookable as the chosen types (see **Lesson-Type Filter**).

+## Lesson-Type Filter
+Not every open slot can be booked as every private-lesson type — a slot tied to
+an offering takes that offering only, and a generic slot only takes types whose
+length fits. The booking calendar therefore carries a lesson-type filter,
+collapsed behind a **Show Only** button that sits in the calendar's control row
+beside the List/Week toggle. Opening it reveals the type list between that row
+and the calendar: a checkbox per active private-lesson type (from
+`GET /offerings?kind=private_lesson`, fetched once per page load), showing the
+instructor's name alongside the title when the catalog spans more than one
+instructor. The button carries the number of ticked types and stays highlighted
+while the filter is on, so a collapsed filter is never invisible. Both button and
+list are hidden when there is only one bookable type.
+
+Ticking one or more types narrows the calendar to the slots bookable as one of
+them; no ticks means no filter, and collapsing the list leaves the filter
+applied. Picking a filtered slot narrows the registration form's **Lesson type**
+picker the same way, and when exactly one type remains it is pre-selected and its
+intake questions load immediately. Changing the filter re-anchors the week view
+on the earliest matching slot, so the student never lands on an empty week.
+**Show all types** clears the filter.
+
+Bookability is decided client-side by `offeringFitsSlot()` in
+`assets/js/booking.js` — the mirror of the rule `POST /bookings` enforces (same
+instructor, the tied offering when there is one, otherwise a matching
+`duration_minutes`). The filter is a browsing aid only: the server re-checks
+every booking regardless.
+
+Two block/shortcode options change what the filter has to work with (see
+`editor-blocks.md`), passed to the script as data attributes on
+`#us-booking-app`:
+
+- **A pinned lesson type** (`data-lesson-type`) narrows the catalog to that one
+  offering, so the page lists only the times bookable as it and books nothing
+  else — the filter control hides itself, there being one type left. A pinned
+  type that is no longer offered shows "This lesson type is not available for
+  booking right now" rather than an empty calendar.
+- **Filter off** (`data-type-filter="0"`) drops the **Show Only** button
+  entirely; every open time is listed, as before the filter existed.
+
+## Embedding Halves of the Page
+The page has two halves — the booking calendar and the student's upcoming
+lessons — and the block/shortcode can embed either on its own (`displayMode` /
+`show`: `both` (default), `booking`, `upcoming`). The template simply omits the
+containers of the half that is not wanted, and the script skips the work that
+belongs to a missing container: an upcoming-only embed never requests
+availability or the offering catalog, and a booking-only embed never requests
+`GET /bookings`. An unrecognised value renders the whole page, so a typo cannot
+silently hide half of it.

+
+So a lesson type reads `50.00 CAD at booking` in the booking form's type picker,
+and a group class card reads `120.00 CAD up front`. A free offering shows `Free`.
+
+**`monthly` reads differently per offering kind, because it *bills* differently.**
+A private lesson's price is a per-lesson fee and its monthly charge is that
+month's lessons × the fee, so the fee is quoted **per lesson**
+(`50.00 CAD per lesson monthly`). A monthly group class is priced **per month** —
+`ScheduledBillingRunner::billGroupMonthly()` charges the fee once for the month
+however many times the class meets in it — so its figure is quoted as it stands
+(`120.00 CAD monthly`). The display split is `isPerLessonMonthly()` in
+`assets/js/pricing.js`; the billing split is the one place the monthly rule
+differs between the two kinds.
+
+Before a booking or enrolment can be submitted, the form shows the price again as
+a summary block with a **required agreement checkbox** — the second confirmation,
+distinct from the policy acceptances above it:
+
+> ☐ I agree to pay 56.50 CAD at booking.
+
+The agreed figure is the amount actually billed, so the studio **HST rate** is
+added to it (`usScheduler.taxRate`, localized from `us_hst_rate`) and broken out
+above the checkbox — matching the total `Payment::total()` charges. A comped
+student is not taxed and is not charged at all, so for them the quoted figure is
+an upper bound. A free offering has nothing to agree to and shows no block.
+
+Cadence-specific wording:
+
+- **Weekly reservation of a `one_time` lesson type** — the fee is charged once per
+  week claimed, so the agreement states the per-lesson amount and the total as a
+  ceiling ("up to 12 lessons, 678.00 CAD in total"). The occurrence count mirrors
+  `BookingEndpoint::MAX_WEEKLY_OCCURRENCES`; a slot another student takes first is
+  simply not claimed, so the real charge can come in under it.
+- **`weekly` / `monthly`** — nothing is taken at registration, so the agreement is
+  to the recurring charge: "I agree to pay 56.50 CAD per lesson, billed monthly."
+  A monthly **group class** agrees to its monthly figure instead ("I agree to pay
+  138.00 CAD monthly."), matching how its price is quoted on the card.
+
+All of this lives in `assets/js/pricing.js` (`window.usPricing`), shared by the
+booking and group-class flows so a price reads the same wherever it is met. The
+script is registered as `us-scheduler-pricing` and is a dependency of both
+`us-scheduler` and `us-scheduler-group`.
+
 ## Payment Flow
 1. During registration the front-end calls `POST /payments/intent` — but only when the registration response carried a `payment` summary (unpriced registrations return `payment: null` and skip the payment step). The intent call creates a Stripe PaymentIntent for a `card` student and returns the client secret. (`etransfer` returns a `pending` payment; `comp` returns none.)
 2. The browser confirms the card payment with Stripe.

 ## Versioning & Acceptance Rules
 - Editing a published policy creates a new `draft` version; the old version stays `published` until the draft is published.
+- Editing a `draft` version rewrites it in place — nobody has accepted it yet, so there is nothing to preserve and no new version is created. `PATCH /policies/{id}/versions/{vid}` allows only this case; the admin page also accepts an edit to a `published` or `archived` version and branches a new draft from it.
 - Publishing a draft sets it `published`, stamps `published_at`, archives the prior version, and points `us_policies.current_version_id` at it.
 - The registration gate requires acceptance of the `current_version_id` of every policy. Because acceptance is tied to `policy_version_id`, a newly published version is unaccepted and must be re-accepted at the student's next booking.
 
 ## Admin Interface
 **Policies** in wp-admin (`manage_policies`, studio admin only):
-- Create a policy; draft and edit version bodies
+- Create a policy; draft version bodies
+- View the content of any version (`?page=us-policies&policy_id={id}&version_id={vid}`), whatever its status
+- Edit from the viewer: a draft is saved in place; editing a published or archived version instead saves the text as a **new draft version** (the viewer follows to it), so text students have already accepted is never rewritten
 - Publish a draft version; view acceptance history per version
 
+## Rendering a Policy Body
+Bodies are typed into a plain textarea, so most are written as blank-line-separated prose with no markup. `PolicyVersion::bodyHtml()` is the single render path — `wp_kses_post()` then `wpautop()`, the same treatment WordPress gives post content — so unmarked-up text arrives as real paragraphs and bodies that do carry markup are left alone. It feeds the booking/enrolment JSON (`GET /policies`), the signup form, and the admin version viewer, which therefore previews exactly what students see.
+
+The acceptance markup (`.us-policy` / `.us-policy-body`) is styled in `assets/css/frontend.css` as a bounded, vertically scrolling reading box with `overflow-wrap: break-word`, so a long policy or a pasted URL cannot force a horizontal scrollbar or push the accept checkbox out of view. `RegistrationPage` enqueues that stylesheet for the signup gate; `BookingPage` and `GroupClassPage` already did.
