preventScroll was blocking the viewport from scrolling to the grid cell
when a clue was clicked from the sidebar. The clue list overflow fix is
sufficient to contain scrollIntoView without needing preventScroll.

Widen quiz, flashcards, practice, test, and crossword views to match the
960px max-width already used by course/lesson/assignment. Fix crossword
jumping to top on cell focus by using preventScroll and containing clue
list scrollIntoView within a max-height overflow container.

Admin enters Across/Down words and clues; server auto-generates the grid
using a backtracking placement algorithm (longest-first, intersection-based).
Students fill in the interactive grid with click-to-select, direction toggle,
arrow-key navigation, and Tab-to-next-word. Auto-graded per word on submit,
with correct/wrong color highlighting on the results view. Includes a print
worksheet option for blank paper practice.

Instructions are optional free text shown to the student above the questions/word bank.
Admin enters them in the item editor; stored in items.body for quiz and matching types.

Bind mount (./data:/app/data) was relative to the working directory,
so data was lost whenever the project was re-cloned or compose was run
from a different path. A named volume is managed by Docker and persists
across container rebuilds and image pulls.

Replaces the plain textarea with a WYSIWYG contenteditable editor so
the formatting the parent sees while writing matches what the student
sees when reading. Toolbar supports bold, italic, underline, H2/H3,
bullet/numbered lists, links, and YouTube embeds. Selection is saved
on editor blur and restored before each execCommand so toolbar clicks
don't lose the user's selection.

Practice: fire streak badge, first-letter hint on wrong answers, missed-words drill session after practice completes.
Test: audio-only mode with listening state before input appears, larger re-read button.
Words: definition field (DB migration + admin editor + TTS playback).
TTS: replace speechSynthesis with local Piper via /api/tts, WAV cached in data/tts-cache, falls back to browser voice when Piper is not installed.
Dockerfile: switched to node:26-slim, installs Piper binary + en_US-lessac-medium voice.
