 ## [Unreleased]
 
+### Changed
+- **UI polish — post-#147 review (#147)** — ten UX fixes across History, Bibliotek, Planlegger, MuscleMap, TemplatePicker, and Login:
+  - **History** — removed username display from exercise edit box; "Legg til øvelse manuelt" and "Last opp nytt bilde" unified as sibling ghost buttons below the exercise list; session header chips capped at 2 visible + `+N` overflow to prevent title overflow; library pre-fetched on mount so autocomplete is always ready; gym-class conflict warning wording clarified
+  - **Bibliotek** — "Maler" tab renamed to "Mine maler"; Snarveier carousel removed (caused horizontal overflow); `used_at` date removed from template cards
+  - **TemplatePicker** — "Sist brukt" date removed from template cards
+  - **Planlegger** — "Lagre plan" and "Fjern uke" buttons removed; plan now auto-saves on every add/remove and auto-deletes when all slots are cleared
+  - **MuscleMap** — "NESTE STEG / Analyser perioden" CTA card removed from result step; "TIPS" callout removed from upload step
+  - **Login** — daily quotes hardcoded to English (language is unknown before sign-in)
+  - **Carbon Select** — global CSS fix strengthened to also force `background-color: var(--cds-field-01)` in default state, preventing white-on-white in all layer contexts
+
 ### Added
-- **Joint class history (#138)** — expanding a gym-linked session in History now shows a "Kolleger i denne klassen" panel listing co-instructor sessions for the same class slot. Display name (or "Instruktør" fallback) is shown as a header per colleague, with their exercise list below. Fetched lazily on first expand and cached per `gym_calendar_id`. New RLS policy on `sessions` allows same-gym users to read each other's shared sessions. `fetchClassHistory(gymCalendarId)` added to `db.js`.
-- **Session privacy (#139)** — `visibility` column added to `sessions` (default `'shared'`). History edit mode gains a Carbon `Toggle` ("Del med andre instruktører") that persists to `visibility = 'private'` on save. Private sessions are excluded from the cross-gym RLS policy and from `fetchClassHistory`. `updateSession` accepts a `visibility` option.
+- **Email templates (#148)** — Supabase auth emails (magic link, invite, email confirmation) are now version-controlled in `supabase/templates/`. Branded with Workout Lens name, `workout.umulig.org` domain, magenta CTA button, and Carbon-matching dark colour scheme. Apply to the remote project with `supabase link` + `supabase config push`.
+- **Joint class history (#138)** — expanding a gym-linked session in History now shows a "Kolleger i denne klassen" panel listing co-instructor sessions for the same class slot. Display name (or "Instruktør" fallback) is shown as a header per colleague, with their exercise list below. Fetched lazily on first expand and cached per `gym_calendar_id`. New RLS policy on `sessions` allows same-gym users to read each other's sessions. `fetchClassHistory(gymCalendarId)` added to `db.js`.
 - **Display name (#141)** — `display_name text` column (max 50 chars) added to `profiles`. Settings → Konto section now has a `TextInput` to set/update a display name, with success/error feedback. Same-gym RLS policy on `profiles` allows co-instructors to read each other's `display_name`. `fetchDisplayName()` and `updateDisplayName()` added to `db.js`. Display name is shown next to colleague sessions in the joint class history view.
+- **GDPR transparency note** — Settings → Konto now shows an informational paragraph explaining that all logged sessions are visible to co-instructors at the same gym, in line with the app's purpose.
 
 ### Changed
+- **Session visibility removed** — the `visibility` / "Del med andre instruktører" toggle has been removed entirely. All sessions logged under a gym are now always visible to co-instructors at the same gym (the intended behaviour). The Supabase RLS policy on `sessions` was updated to remove the `visibility = 'shared'` filter; all existing private sessions were backfilled to shared. `updateSessionVisibility` removed from `db.js`.
+- **History — always-on inline editing** — sessions are always editable when expanded; the "Rediger økt" button and locked read state are gone. A sticky Save / Discard / Reupload bar appears automatically when any change is detected (dirty state). Fixes the filter+edit bug where an active muscle filter prevented entering edit mode. The muscle groups section (redundant with the body map) is removed from the expanded view. "Re-analyser" renamed to "Last opp nytt bilde".
+- **Edit panel visual consistency (#147)** — all edit/entry containers now share the same surface treatment: `var(--cds-layer-02)` background + 2px `var(--accent)` top border + `SectionLabel` with icon header. Applies to `ExerciseForm`, `TemplateSessionEditor`, and the MuscleMap confirm step. Cancel buttons changed to `kind="ghost"`, errors shown as `InlineNotification kind="error"` above the button bar. `SectionLabel` now accepts a `renderIcon` prop.
+- **Template use flow** — "Lagre mal" is no longer shown in the template use flow (Planlegger → Bruk økt). A step indicator ("Steg 2 av 3 — Tilpass øvelser") is shown instead. Template name input replaced with Carbon `TextInput`.
+- **Report — restructured layout** — the "Ikke trent" gap card is now positioned after the muscle frequency table, directly above the recommendation button, acting as a visual header for the recommendation section. The post-recommendation body map (`BodySVG`) is removed. Fallback messages added: if all primary muscles are trained the gap section shows a success message; if some are secondary-only only those are listed.
+- **Library — scaling** — the Snarveier carousel is capped at 6 items with a "Se alle →" link to the templates tab. Load-more buttons (20 exercises / 12 templates per batch) appear when lists exceed their threshold. A search input is added to the templates tab.
 - **Test suite — better coverage, less noise** — replaced low-value assertions (one-line constant checks, per-model `it`s, a duplicated prompt assertion) with behavioural tests, and filled the largest gaps in `utils.js` (date helpers `toIsoDate`/`toWeekIso`/`weekIsoToMonday`/`isoWeekMonday`, `isInvalidNum`, `extractMuscles`, `getIntlLocale`, `inferMusclesFromName`) and `prompts.js` (`buildMuscleInferencePrompt`). Added a fake-timer test for `checkRateLimit` window expiry. Net: 60 → 82 tests; `utils.js` line coverage ~30% → ~80%, `prompts.js` to 100% statements.
