Три проблемы UX отключения модулей:
1) Пустой блок флешкарт на дашборде: виджет #w-flashcard — <div>, а скрытие шло
только по [href]. Добавлена карта FEATURE_WIDGETS (флешкарты→#w-flashcard) —
контейнер прячется целиком.
2) Лаборатория не уходила из сайдбара: не было ГЛОБАЛЬНОГО тумблера lab (только
free-student). Добавлен в whitelist updateFeatures + GAME_FEATURES; map уже знал
lab→/lab. Теперь выключение скрывает пункт и редиректит со страницы.
3) Мигание выключенных модулей (FOUC): hideDisabledFeatures асинхронный. Теперь
loadFeatures кэширует /api/features в localStorage, а _applyFeatureCss инъектит
<style id=ls-feat-hide> синхронно из кэша на ранней загрузке (api.js идёт до
sidebar.js) — сайдбар/виджеты строятся уже скрытыми. Геймификация: класс
no-gamification ставится на <html> (раньше body), ls.css правило body.no-gamification
→ .no-gamification (работает и для html, и для body).

Аудит выключателя геймификации выявил элементы, НЕ покрытые body.no-gamification:
испытания недели (#ch-section/.ch-widget), календарь стриков (.streak-cal),
стат-кольцо стрика (#sr-streak), монеты в профиле (#p-coins-row), чипы стрик/цель
на карточке питомца. Добавлены в CSS kill-switch (ls.css). Бэкенд: updateChallenges
и onLabExperiment писали прогресс/счётчики без проверки флага — добавлен гейт
isGamificationEnabled() (XP/coins/achievements уже гейтились в award*-функциях).

Linear-gradients tiled at 3px wide produced striped curtains, not
rain. Switched to two pseudo-element layers of elongated radial
ellipses (1.5px × 12-18px) scattered across 130-180px tiles —
sparse drops at two depths with different fall speeds.

Doubles the bg catalogue from 10 to 19 with richer multi-layer
animations. Every keyframe pack is CSS-only and respects the existing
prefers-reduced-motion fallback.
sunset 550 slow hue cycle through warm palette
rain 650 2-layer vertical streaks at different speeds
snow 700 3-layer drifting flakes pattern
clouds 750 drifting white blobs on day sky (only LIGHT one)
fireflies 800 pulsing glowing dots, opposing drift
cyber-grid 850 neon grid scrolling down with vignette
kaleidoscope 1000 two huge conic-gradients in opposite rotation
ocean 1100 layered blobs drift like undulating waves
aurora-dance 1500 multi-band aurora — new premium top-tier
Tonal classification mirrored in api.js DARK_BG_SLUGS so the veil
picks the right contrast: clouds is light, the other 8 join the dark
set (alongside dark, stars, aurora, nebula, grid).
Each background also gains a matching .bg-preview.bg-<slug> rule that
reuses the same animation at the shop's 90px swatch — WYSIWYG.

The pill containers (.p-tabs, .shop-filters) used a 6% black fill that
disappeared on the dark veil, so the rounded button group lost its
outline and the inactive tabs looked like floating text. Same for the
xp / progress tracks (.ach-xp-progress, .ep-bar, .po-bar) that used
7% black.
Dark-tone overrides:
• Containers get a 6% white wash + 10% white border so the pill
shape stays readable
• Inactive p-tab gets the same color/hover treatment that .shop-filter
already had (was an oversight in the previous fix)
• Active pills gain a darker shadow halo so they don't look detached
• Progress tracks switch to a 10% white track instead of 7% black

The dark veil was right (deep navy at 78%), but every page chrome
element below it inherited light-theme text colors and faded to
invisible — 'Магазин наград' header, shop filter buttons, achievement
group titles, balance counter etc.
Targeted overrides for body[data-bg-tone='dark']: only the elements
that sit directly on the veil get a light text color. White cards
(.shop-item, .ach-item, .ep-card) keep their dark text intact.

The single bg-fx layer was painting at full vibrancy behind the entire
app. Most UI elements use rgba() fills — chips, sub-panels, the
achievements .ach-item, the goal-tier bar — so saturated colors bled
right through, hurting readability on the Достижения / dashboard /
mocks tabs.
Layered fix:
• bg-fx drops to z-index:-2 (the animated layer)
• new #ls-bg-veil sits on z-index:-1 with rgba(245,247,251,.78)
(light) or rgba(15,23,42,.55) when body[data-bg-tone='dark']
• applyCosmetics injects both elements and tags the body with
bg-tone based on the slug (dark/stars/aurora/nebula/grid go dark,
everything else light)
• clearing the bg removes both layers + the tone attribute
Result: animations stay perceptible (~22% of the chosen palette comes
through the veil), but the page chrome reads at normal contrast.
Shop swatches keep full vibrancy — the .bg-preview is meant to show
the raw palette so users can compare.

A new cosmetic family: a fixed-position overlay painted behind every
page of the app, switchable from the profile shop. 4 free presets + 6
paid (250-1200 coins) so the new economy has another sink. Every
animation respects prefers-reduced-motion and falls back to its static
gradient.
Catalogue (migration 035):
free: none, gradient-soft, dots, dark
paid: gradient-flow, grid, bubbles, stars (mid)
aurora, nebula (premium)
Backend:
• migration 035 adds users.active_background + rebuilds shop_items
CHECK to include 'background' (standard SQLite 'new + copy + swap')
and seeds 10 items
• shopController.getMyActive returns { background: { slug } } and
activateItem handles type='background' (stores bare slug in
active_background) + skips the user_purchases check for price=0
so free presets work for everyone without per-user rows
• routes/shop validate schema lets 'background' through
Frontend:
• api.js applyCosmetics injects <div id='ls-bg-fx'> at body start
and toggles class to bg-<slug>. Cleared backgrounds remove the
element so dark→light transitions don't leave artifacts.
• ls.css gains a self-contained 'ANIMATED BACKGROUNDS' block:
keyframes per animated slug (ls-bg-flow, ls-bg-grid-scan,
ls-bg-bubble-rise, ls-bg-stars-twinkle, ls-bg-aurora-spin,
ls-bg-nebula-pan) wrapped in a prefers-reduced-motion kill-switch.
Same .bg-<slug> classes are reused for the .bg-preview swatches.
• profile.html shop:
- new 'Фоны' filter button between Рамки and Титулы
- _renderItemPreview type='background' draws a real 56-aspect swatch
(same CSS as the page bg — what you see is what you apply)
- _isItemActive matches by slug for background type
- free items (price===0) treated as auto-owned in render so users
can apply them without a fake 'purchase' step
Verified: getMyActive returns { background: { slug: 'nebula' } } after
flipping users.active_background; activate path updates the row.

Until now the 'gamification' feature flag did nothing: it had no row in
app_settings, the admin couldn't toggle it, awardXP/awardCoins ignored
it, and the CSS only hid three dashboard widgets — XP bars in textbooks
stayed visible regardless.
Phase 1 closes every hole.
Backend (source of truth):
• migration 029 seeds feature_gamification_enabled=1
• new isGamificationEnabled() helper in gamification/_shared.js with a
30s cache + invalidateGamificationCache() for instant admin toggles
• awardXP / awardCoins / updateStreak / unlockAchievement /
checkAchievements all bail out when the flag is off
• /api/gamification/* and /api/shop/* (user routes) return 404 when
disabled; admin routes remain open so the switch itself is reachable
• adminController.updateFeatures gains 'gamification' in the allow-list
and invalidates the cache on flip
Frontend:
• LS.isGamificationEnabled() (synchronous, populated by loadFeatures)
so xp.js + applyCosmetics can bail without a round-trip
• xp.js load/add/flush become no-ops when the flag is off
• applyCosmetics skips the round-trip when off
• CSS .no-gamification rule expanded to cover .hero-xp-badge, .po-xp,
.xp-card, .xp-bar, #frames-section, and a universal [data-gamified]
hook for future blocks
Textbooks (Variant 2 of the plan):
• backend/scripts/wrap_textbook_xp.py — idempotent script that adds
data-gamified to 167 XP tags across 63 textbook files (chapters +
hubs, all subjects/grades). Single CSS rule now hides everything.
Verified end-to-end: with the flag off, awardXP/awardCoins write nothing;
flipping back restores normal behavior.

Shop items of type 'frame' now render a real avatar-sized preview with
the frame's CSS applied (instead of a generic lucide icon) so buyers
see exactly what they're paying for. Title items get a tag-shaped
preview in their color. The avatar-frames section above the shop also
shows the user's actual avatar inside the frame circles, not 'LS' text.
Sidebar nav-avatar now:
• renders the uploaded avatar_url instead of always showing initials
(LS.initPage + new LS.refreshNavAvatar helper)
• picks up frame CSS on every page via applyCosmetics — previously
only dashboard.html applied it
• repaints immediately after picking/deleting an avatar preset
(avPickPreset / avDelete now call LS.setUser + LS.refreshNavAvatar)
Backend getMyActive resolves avatar_frame to {id, css} for both
gamification frames ('fire', 'crown', ...) and shop-purchased frames
('shop_<id>'), so the client doesn't need a second round-trip to
look up the CSS.

- Add js/sidebar.js: generates full sidebar HTML into #app-sidebar,
handles role-based visibility, active link (with prefix matching),
toggle wiring, collapsed state, board/features/notif init
- Replace <aside class="sidebar">...</aside> with <aside id="app-sidebar">
across all 35 standard-layout pages via scripts/apply-sidebar.js
- Add notifications.js to 5 pages that were missing it
- Fix api.js initPage(): skip toggle re-wiring if data-sb-wired set,
fix active link selector .sb-item → .sb-link
- Remove stale sbl-*/nav-admin/btn-upload-nav getElementById calls
that crashed after sidebar replacement (lab, classes, collection,
crossword, hangman, knowledge-map, library, pet, profile)
