Mobile only (<=639px / coarse pointers); desktop keeps its behaviour.
Foundation
- lib/motion.ts owns the spring presets (snappy/gentle/sheet), durations,
easings and variants (screens, tabs, wizard steps, list stagger).
- Native-feel CSS: press feedback scales every button, card, chip, tab,
row and summary to 0.96 with a spring-like cubic-bezier on transform
(scoped to phones/coarse pointers), tap-highlight off, touch-action
manipulation, chrome text non-selectable, reduced motion drops it.
- App shell fades in once on launch; the study feed fades in on phones.
Applied
- Tab bar: sliding active pill (shared layoutId) + icon bounce.
- Study Decks/Homework, language toggle, difficulty and size pickers:
the same gliding highlight, gated so desktop keeps the old styling.
- Route content enters direction-aware (deeper = from the right, back =
from the left, same-depth = crossfade) via RouteTransition on the
library/create/homework content columns; library tab switches
crossfade; wizard steps slide forward/backward (reduced motion safe).
- Library: cards fade up in a capped stagger on first load, glide with
layout animations and shrink away on delete (AnimatePresence).
- Study feed: correct feedback pulses, wrong shakes, the progress bar
settles with a spring curve, score and XP count up on the results.
- Settings sheet uses the sheet spring; the drawer now follows the
finger and closes on release velocity, like the sheet.
- Generation progress: the stage message fades/slides between stages;
the icon keeps its gentle wobble; the feed fades in on hand-off.
Skipped, on purpose: LazyMotion (the sliding highlights need layout
animations = domMax, same features the current import already has);
route exit animations (the App Router unmounts the outgoing page —
exits are handled by in-page AnimatePresence); replacing the study
feed's native scroll-snap with finger-follow drag (would fight the
platform scroller); finger-follow height animation for native <details>
expanders.
Verified: animation suite 8/8 (reduced motion + 4x-CPU-throttled trace:
no long tasks, CLS 0.0000), regression 74/74, mobile 52/52, declutter
116/116, i18n 25/25. Lint + build clean. SW freezmo-v21.
Library ("Your icebox")
- Two tabs, never mixed: Study Decks (the folder + card library) and Homework
(saved solutions and step-by-step guides). The active tab lives in the URL
(/?tab=homework), so the sections are linkable and survive a reload.
- Decks tab keeps Import, the folder bar, stats and its own empty state — now
a single decks-only CTA.
- Homework tab lists saved results as cards (mode icon, date, step count,
preview) with Open and delete-with-confirm; its empty state has its own CTA
("Homework Solver") that opens the solver directly. Opening a card
deep-links to /homework?open=<id>, which the screen opens on arrival.
- .segmented now also styles link segments (same control as settings).
/create
- The redundant "Study Deck | Homework Solver" toggle is gone: /create is the
deck uploader only, and the bottom bar's + goes straight to it. Homework has
its own screen, reached from the library tab, the drawer and CTAs.
Copy
- New keys (en + cs): tabDecks, tabHomework, homeworkHeroTitle, plus homework
empty-state/open/step-count strings. The homework hero is now "Solve your
homework" / "Vyřeš svůj úkol" — no study-deck text in the homework flow.
- Removed the now-unused ModeSwitch component and homework.title key.
Service worker: freezmo-v10.
Verified: library-tabs suite 37/37 (tab switching, context empty states,
deep-link opening, deletion, no switch on /create, heroes, redirects, desktop
grid, 360px + 44px targets, axe contrast en+cs light+dark), mobile 49/49,
i18n 27/27, desktop regression 74/74. Lint + build clean.
Terminology (lib/i18n-dict.ts)
- One name per mode everywhere: "Study Deck" / "Studijní balíček" and
"Homework Solver" / "Řešitel úkolů". The library empty-state cards and the
/create switcher now read the same, so the choice no longer changes name
between screens.
Deep links
- Library quick actions carry the mode: /create?mode=deck and
/homework?mode=homework.
- Both pages canonicalize: /create?mode=homework redirects to the homework
flow and /homework?mode=deck redirects to /create, so a mode link always
opens that mode directly.
/create
- The two bulky square cards (106px tall, wrapping/clipping "Study Deck &
Qu…" on phones) are replaced by a compact segmented control (52px) placed
directly above "1. Add your notes": ice pill, snowflake/sparkles icons,
44px segments and one-line labels at 360px. The pill slides to the chosen
segment and the route follows ~190ms later, so toggling reads as one smooth
transition (immediate under prefers-reduced-motion).
Service worker: freezmo-v9.
Verified: mode-switch suite 26/26 (deep links, cross-mode redirects, 52px
control, 44px segments, no clipping/wrapping at 360px, "1. Add your notes" at
y=394 of 740 with the upload controls above the fold, pill slide, axe contrast,
en+cs, phone+desktop), mobile 49/49, i18n 27/27, desktop regression 73/73.
Lint + build clean.
Homework (/homework — entry points in the drawer and on the create screen)
- Assignment intake reuses the study pipeline: pasted text, photos
(camera/picker, compressed in the browser) and documents (PDF/DOCX/PPTX/
ODT/text) through lib/image + lib/documents, the same vision step and the
same language guard. Raw files never leave the device — only text and JPEG
data URLs reach the server.
- Two large choice cards: “Just make it” returns the finished homework
(answer only, plain text, copy + make it again); “Explain how to make this
homework” builds an interactive guide.
- The guide is one step per screen in the study-feed snap layout:
explanation, three progressive hints (nudge -> hint -> the answer) and an
optional checkpoint rendered by the existing activity components (graded
through /api/grade). The last screen assembles the solution from the step
answers, with a copy button. Checkpoints carry xp 0 so the guide stays free
of XP/streak chrome.
- Results live in freezmo.homework.v1 with a small history (open/delete);
“Make it again” re-runs from the stored assignment text (the vision
transcription when photos were used) — no original files are stored.
- The answer and the guide are written in the assignment's language, never
translated into the UI language.
Server
- POST /api/homework: NDJSON stage events like /api/generate, the same
http-guard, auth checked before parsing, and its own RATE_LIMIT_HOMEWORK
(documented in .env.example + the README table).
- New prompts in lib/prompts.ts and zod schemas in lib/schemas.ts with the
same single repair retry; TEXT_MODEL for content, VISION_MODEL only for
photos. New shared client pieces: useNotesIntake, lib/homework store,
lib/clipboard, and a shared NDJSON reader in lib/client-api.
Also finishing the mobile polish pass from the previous request
- Phone ice scene: the top-left orb moved behind the glass header (it sat
behind the page heading/subtitle). The settings sheet's scroll cue is now a
bare chevron inside a content fade (mask) instead of a chip over the status
banner, and the API key card's note/disclosure/actions are tightened.
- theme-color now follows the in-app theme (SSR metas still fall back to the
OS preference); apple-mobile-web-app-status-bar-style stays “default”
because iOS fixes the status-bar text colour at launch.
Verified: 78/78 homework checks (text/photo/PDF, both modes, EN+CS, dark+light,
360/390px, copy, history persistence, storage privacy, API language, axe), plus
the existing suites re-run (mobile 47/47, pixel contrast 0 below AA, i18n 27/27,
desktop regression 72/72). Lint + build clean; service worker freezmo-v6.
