Three drill upgrades: in-session requeue, spoken models, and a weak-spots view
On top of the spaced-repetition drills: cards you miss now reappear within the same session, the model sentence is spoken aloud so you can shadow it, and a weak-spots dashboard surfaces what you keep getting wrong — all from data the daily grade already collects.
With SRS persisting on the account, three quick upgrades made the drill loop noticeably better to actually use every day.
In-session requeue. Hitting Again now pushes that card to the end of the current session, so you keep meeting it until it sticks — instead of moving on and not seeing it for a day. The subtlety: SRS still scores only the first attempt per card in a session. So the Leitner box reflects genuine recall, not in-session grinding; the requeue is pure reinforcement and doesn't inflate your stats.
Spoken models (TTS). The drills were text-only, which is odd for a shadowing tool. The model sentence is now spoken on reveal via the browser's Web Speech API — free, no key, slightly slowed for shadowing — with a 🔊 replay button. Hear it, say it.
Weak-spots dashboard. A new /weak view (linked from the Practice hub) lists the cards you miss most, sorted by lapses, with seen / total-misses / mastered stats across the deck. It's deliberately read-only: the daily grade already records every miss, and low-box cards already come back sooner on their own — so this is the X-ray, not another thing to manage. A new lib/practice-cards.ts became the single source of truth for card keys, so the drill pages and the dashboard can't disagree about what a key means.
A dev-environment note worth recording (it cost real time, twice): every locale route started 404'ing in dev. Cause was nothing in the code — a sibling Next project squatted on :3000, so requests were hitting the wrong app, and a stray next build against the live dev server had corrupted .next. Fixed by pinning this app to port 3100 and clearing .next. When a route you know exists 404s but the server still answers, check which app owns the port before touching routing.
