feat: add a Tools page printer for note merge and print presets

Chapter officers can merge a markdown note onto filtered students, teams, or events and save the recipe. Extra student-note columns are additional fields (any ## … fields heading) so they work as print tokens whether imported or typed by hand.

+# Page printer
+
+**Created:** 2026-08-29  
+**Last updated:** 2026-08-30  
+**Description:** Merge a markdown note onto students, teams, or events and print one page per match. Save the recipe as a print preset.
+
+## Where to open it
+
+Sign in and go to **Tools → Page printer** (`/print`).
+
+## Write a template note
+
+Create a standalone note on **Notes** (not a page note or student note). Use `{{tokens}}` for values. Click a token chip on the printer page to copy it.
+
+```markdown
+# Interview — {{FirstName}} {{LastName}}
+
+| Grade | Interview Time | Application |
+| --- | --- | --- |
+| {{Grade}} | {{Interview Time}} | {{Application}} |
+
+1. Why did you join TSA?
+2. What events interest you?
+```
+
+Unknown tokens stay visible so typos are obvious. Empty values (including a missing Interview Time) print blank.
+
+Put `{{PageBreak}}` on its own line to force a new printed sheet **inside** one record (for example, questions on page 1 and a scoring rubric on page 2).
+
+Put `{{AnswerSpace}}` where you want ruled write-in lines. Markdown collapses blank lines, so extra empty lines in the note will not leave room to write.
+
+Additional-field tokens use the same names as the Students index columns (for example `{{Interview Time}}`). Those values come from each student's `#Student:{id}` `## Additional fields` table. See [student-notes-import.md](student-notes-import.md).
+
+## Filters
+
+Pick **Students**, **Teams**, or **Events**, then optional filters.
+
+For students: Grade, TSA year, and officer (any / officers only / non-officers). Example: TSA year `1` prints first-year students. `{{OfficerRole}}` still prints the office name when they have one. Additional fields such as Interview Time are merge tokens, not filters. Student pages sort by last name, then first name.
+
+## Print presets
+
+A print preset stores the *recipe* only: name, template note, entity type, and filters. It does not store merged pages. Each Preview uses the current roster and notes.
+
+1. Set the note, entity, and filters.
+2. Enter a name and click **Save as**.
+3. Later, choose a preset, click **Preview**, then **Print**.
+4. **Update** overwrites the selected preset. **Delete** removes it.
+
+If the template note was removed, the filters still load. Choose another note before Preview.
+
+## Print
+
+**Preview** builds the pages. **Print** opens the browser print dialog (same as other handouts). Navigation is hidden.
+
+**New page per record** (on by default, saved with the preset) starts each match on a new sheet. Turn it off to flow records together; `{{PageBreak}}` in the template still works. Content that is taller than one sheet continues naturally.
+
+**Font size (pt)** (default 12) and **Answer lines** (default 3) apply to every page-printer recipe. They are saved on the preset.
+
+If Preview finds more than 75 matches, a warning is shown first.
