Mobile Phases 4–5: Pipeline (swipe-between-stages) + Reminders

Completes the four mobile-first surfaces. Both phases follow the established
useIsMobile() wrapper → Mobile*/Desktop* pattern; desktop is untouched (only
renamed Desktop*). No backend change.

P4 Pipeline (MobilePipeline): CSS scroll-snap swipe between the four stages +
count-forward segmented control + page dots; per-card ‹/› stage move and
tap → full-screen opp detail with a stage-picker sheet. Opp-centric — shares
PATCH /api/opportunities/{id}/stage with the desktop board and the Grid's
stage edit; view + advance-stage only (removal stays on the Grid/desktop board).

P5 Reminders (MobileReminders): urgency-grouped list over /api/reminders
(Overdue/Due soon/Later/Done/Cancelled) with an Active/Done/All filter; each
row is a pointer-drag swipe (left = mark done, right = snooze +7d, keeping
status open and pushing due_date, per the desktop rationale); tap → create/edit
BottomSheet (investor is create-only, matching the backend PATCH field set).
formatDueShort/reminderDueDelta fix the desktop formatter mis-rendering future
due dates.

Verified: render-smoke + throwaway jsdom 375px interaction harnesses (12/12
each); reviewer passes applied — notably P5 pointercancel no longer fires a
spurious mark-done. Deploy-pending (no s9pk built); not yet tested on a phone.

 - **Live (deployed):** W2 NL query (v94; remaining: in-room smoke + web "Ask" box); W1 reminders (v93); grid Pipeline (v88); Matrix intake + Gmail capture (DWD) + daily digest; Thesis/Architect (dual-approval); outreach — all draft-only.
 - **Tests:** **36/36 backend green** (`python3 backend/run_tests.py`), `py_compile` clean, render-smoke green, fresh-DB migrate clean.
-- **Next:** 1) **P4 Pipeline** (swipe-between-stages; reuses the opportunities endpoints + `<BottomSheet>`/`StageChip`); 2) **P5 Reminders → P6 light theme**; 3) **P3b** name/pill edit; 4) **deploy** P0–P3a + view-reorder in one s9pk (**authorize first**); 5) W2 web Ask box + smoke; 6) W3 bot grid-mutations; 7) W1b nurture-gap.
+- **Next:** 1) **P6 light theme** (inline-hex→`var()` axis, 183 literals + ship `color.light` behind a `[data-theme]` toggle; dark stays default); 2) **P3b** name/pill edit (narrow per-row PATCH + pill editor); 3) **deploy** P0–P5 + view-reorder in one s9pk (**authorize first**) — verify on a real phone; 4) W2 web Ask box + smoke; 5) W3 bot grid-mutations; 6) W1b nurture-gap.
 - **Open / risks:** all mobile work **built but never deployed or tested on a real phone** (render-smoke + jsdom-at-375px only — verify on a device); **P3b deferred**; W2 happy-path only; **Claude/Architect path unverified live on the box**; v2.0 reserve-asset spine **not canonical** (needs dual sign-off); doc drift — `crm-overview.md`/`EVALUATION.md` still call `lp_profiles` live.
