Lands Phase D4 (F10–F14, F16) from the design pass. All six D4 items are ticked in docs/IMPLEMENTATION_PLAN.md.

History (F10, F11)

• Cards: date line with a gold PR chip, the routine name in large type, a row with the timer icon, duration, sets and volume, then the first three exercises and "+N".
• List / Calendar switch: now an icon beside the title.
• Calendar: trained days are tinted in three steps by the day's volume (thirds of the month's busiest day). The picked day is filled with primary and today always keeps its ring. A "Less … More volume" key sits under the grid.

Workout detail (F12)

• Duration, volume and set tiles; Delete moves into the ⋮ menu.
• An exercise with nothing done is a one-line "Skipped" card. Others end with "N planned sets skipped".
• Exercise names open their history on a new history/exercise/{id} route, so History stays selected.

Exercises (F13)

• Material 3 search bar ("Search 69 exercises"), and an Equipment chip with a menu, placed first in the row so it's on screen.
• Each trained exercise shows "Last 82.5 kg × 8 · today", from the last finished workout with a non-warm-up set.

Exercise detail (F14)

• Hero card with the latest session's best e1RM, a Canvas sparkline of every session's, and "+4.2 kg in 30 days". The change is against the last session at least 30 days old, and hidden until there is one.
• Records as a grid of tiles: Heaviest, Most reps, Best e1RM, Session volume, each with its date.

Exercise picker (F16)

• Recent chip first, then All and the muscle groups. Recent is the exercises of the last 5 finished workouts, on by default when there are any. A search under Recent looks through the whole library.
• Picks are numbered in tick order, with a tray of removable picks above Add.
• The logger and the routine editor share it.

Data

No schema change. New queries:

• WorkoutDao.observeHistoryExerciseNames()
• WorkoutDao.observeLastSessionSets()
• WorkoutDao.observeRecentExerciseIds()

Branch note

The branch merges its old, already squash-merged D3 commits instead of force-pushing over them, so the diff against main is D4 only.

Checks

./gradlew testDebugUnitTest ktlintCheck lintDebug assembleDebug passes with 238 tests. New tests cover:

• calendar volume steps, the Equipment filter, the e1RM trend and its 30-day change, and picker options
• the three new queries
