Four features: outbound link markers, offline content, log text/photo, departure picker

Learn tab
- ic_open_in_new.xml: external link icon (box + arrow) applied to all browser-opening cards
- Migration guide cards retain internal › chevron; ASA/Flashcards cards show ↗ icon
- New REFERENCE section (offline, works without connectivity):
  - ColRegs Rules of the Road → colregs_reference.md (rules 1–38, lights table,
    sound signals, day shapes, memory aids)
  - Sailing Quick Reference → sailing_reference.md (points of sail, Beaufort scale,
    nav lights, knots, buoyage IALA-B, VHF channels, distress signals, tide rule of 12)
- ColRegs card moved from external ASA section to offline REFERENCE section

Log entry
- LogEntry: add photoPath field (absolute file path or content URI string)
- VoiceLogViewModel: replace confirmAndSave() with save(text, photoPath?) so the
  fragment controls text (user may edit recognized speech before saving)
- VoiceLogFragment: redesigned layout with EditText (editable, voice fills it),
  camera button (TakePicturePreview → JPEG in cacheDir), gallery button (GetContent),
  photo thumbnail with remove button, Save / Clear row
- Manifest: add android.hardware.camera uses-feature (required=false)

Departure date/time picker (trip planning)
- ic_calendar.xml: calendar icon for the picker button
- PreTripReportViewModel: _departureMs StateFlow (default = now), setDeparture(ms)
- PreTripReportGenerator.generateReport(): departureDateTimeMs param;
  findDepartureSlot() matches nearest UTC forecast item; condition window labels show
  actual local times (e.g. "2 PM") when departure is not near-now; buildWatchList
  uses departure hour for Kona trades warning instead of system clock
- fragment_pretrip_report.xml: DEPART card with label + calendar button above generate
- PreTripReportFragment: MaterialDatePicker (future dates only) → MaterialTimePicker
  chain; auto-regenerates after picker confirms

+# ColRegs — Rules of the Road
+
+International Regulations for Preventing Collisions at Sea (COLREGS), 1972 with amendments. This is a summary reference; consult the official text for legal purposes.
+
+---
+
+## Part A — General (Rules 1–3)
+
+**Rule 1 — Application**
+Applies to all vessels on the high seas and connected navigable waters.
+
+**Rule 2 — Responsibility**
+Nothing in these rules exonerates a vessel, owner, master, or crew from the consequences of neglect. Good seamanship always applies.
+
+**Rule 3 — Definitions**
+- *Vessel* — any watercraft, including seaplanes and WIG craft
+- *Power-driven vessel* — any vessel propelled by machinery
+- *Sailing vessel* — under sail only; if engine is running, she is power-driven
+- *Vessel engaged in fishing* — using nets, lines, trawls that restrict maneuverability
+- *Underway* — not at anchor, aground, or made fast to shore
+- *Restricted visibility* — fog, mist, falling snow, heavy rain, sandstorm, or similar conditions
+
+---
+
+## Part B — Steering and Sailing Rules
+
+### Section I — Conduct in Any Visibility (Rules 4–10)
+
+**Rule 4** — Applies in any condition of visibility.
+
+**Rule 5 — Look-out**
+Every vessel shall maintain a proper look-out at all times by sight, hearing, and all available means.
+
+**Rule 6 — Safe Speed**
+Every vessel shall proceed at a safe speed. Factors: visibility, traffic density, vessel maneuverability, background lights at night, radar state, sea state.
+
+**Rule 7 — Risk of Collision**
+Risk exists if the compass bearing of an approaching vessel does not appreciably change. When in doubt, assume risk exists.
+
+**Rule 8 — Action to Avoid Collision**
+- Action must be positive, made in ample time, and large enough to be readily apparent
+- Course or speed changes should be large enough to be noticed
+- If necessary, stop or reverse
+
+**Rule 9 — Narrow Channels**
+- Keep to the starboard side of a narrow channel
+- Vessels under 20 m or sailing vessels shall not impede vessels that can safely navigate only in the channel
+- Overtaking only when safe and the overtaken vessel signals agreement
+- Do not cross a narrow channel if it impedes a through-traffic vessel
+
+**Rule 10 — Traffic Separation Schemes**
+- Join/leave at end; if joining from side, at acute angle
+- Keep out of separation zones
+- Crossing traffic does so at right angles where practicable
+- Inshore traffic zones: use only if < 20 m, or sailing, or fishing
+
+---
+
+### Section II — Conduct in Sight of One Another (Rules 11–18)
+
+**Rule 11** — Applies to vessels in sight of one another.
+
+**Rule 12 — Sailing Vessels**
+- Vessel on port tack gives way to vessel on starboard tack
+- Both on same tack: windward vessel gives way to leeward vessel
+- Port tack vessel cannot determine which tack the other is on: gives way
+
+**Rule 13 — Overtaking**
+Any vessel overtaking gives way. Overtaking means coming up from more than 22.5° abaft the other's beam. Overtaking status persists until clear and past.
+
+**Rule 14 — Head-on Situation**
+Both vessels altering course to starboard so each passes on the port side of the other. Applies when risk of collision exists and vessels are nearly end-on.
+
+**Rule 15 — Crossing Situation**
+The vessel that has the other on its own starboard side gives way (the "burdened" or give-way vessel). The stand-on vessel is on the right.
+
+**Rule 16 — Action by Give-way Vessel**
+Take early and substantial action to keep well clear.
+
+**Rule 17 — Action by Stand-on Vessel**
+- May take action to avoid collision by own maneuver alone when it becomes apparent the give-way vessel is not taking sufficient action
+- Must take action when collision cannot be avoided by give-way vessel alone
+- Course change to port for a vessel on your port side is avoided if possible
+
+**Rule 18 — Responsibilities Between Vessels**
+
+Hierarchy (higher number gives way to all above):
+1. Vessel not under command (NUC)
+2. Vessel restricted in ability to maneuver (RAM)
+3. Vessel constrained by draft
+4. Vessel engaged in fishing
+5. Sailing vessel
+6. Power-driven vessel underway
+
+*Note:* Sailing and power vessels give way to NUC, RAM, constrained, and fishing vessels. A power vessel gives way to a sailing vessel.
+
+---
+
+### Section III — Conduct in Restricted Visibility (Rule 19)
+
+**Rule 19 — Restricted Visibility**
+- Proceed at safe speed adapted to conditions
+- Have engines ready for immediate maneuver
+- On hearing fog signal apparently forward of beam: reduce to bare steerage or stop
+- Avoid alteration of course to port for a vessel forward of beam (except overtaking)
+- Avoid alteration toward a vessel abeam or abaft beam
+
+---
+
+## Part C — Lights and Shapes (Rules 20–31)
+
+### Lights (Rules 20–22)
+
+**Rule 20 — Application**
+Lights required from sunset to sunrise and in restricted visibility.
+
+**Rule 21 — Definitions**
+- *Masthead light* — white forward light, 225° arc
+- *Side lights* — red (port) and green (starboard), 112.5° each
+- *Stern light* — white aft, 135° arc
+- *Towing light* — yellow, same arc as stern light
+- *All-round light* — 360° arc
+- *Flashing light* — 120+ flashes/minute
+
+**Rule 22 — Visibility of Lights**
+
+| Vessel size | Masthead | Side | Stern | All-round |
+|---|---|---|---|---|
+| ≥ 50 m | 6 nm | 3 nm | 3 nm | 3 nm |
+| 12–50 m | 5 nm | 2 nm | 2 nm | 2 nm |
+| 7–12 m | 3 nm | 1 nm | 2 nm | 2 nm |
+| < 7 m | — | — | — | 2 nm |
+
+---
+
+### Light Combinations to Know
+
+**Under power (≥ 50 m):** Two masthead lights (forward lower, aft higher) + sidelights + stern light
+
+**Under power (< 50 m):** One masthead light + sidelights + stern light
+
+**Under sail (underway):** Sidelights + stern light only. *No masthead light when under sail.*
+
+**Sail + engine:** Power-driven vessel rules apply — show cone (point down) by day.
+
+**At anchor (< 50 m):** One white all-round light forward.
+**At anchor (≥ 50 m):** White all-round forward + aft.
+
+**Not under command:** Two red all-round lights (vertical). If making way: add sidelights + stern light.
+
+**Restricted in ability to maneuver:** Red-white-red all-round lights (vertical). If making way: add masthead + sidelights + stern.
+
+**Vessel aground:** Anchor lights + two red all-round lights (vertical).
+
+**Towing vessel:** Extra masthead light(s) + yellow towing light instead of (or in addition to) stern light.
+
+**Fishing (trawling):** Green over white all-round (vertical) + sidelights + stern if making way.
+**Fishing (other):** Red over white all-round (vertical) + sidelights + stern if making way + white toward gear if gear > 150 m.
+
+**Pilot vessel on duty:** White over red all-round lights.
+
+---
+
+### Day Shapes (Rule 28)
+
+| Shape | Vessel Type |
+|---|---|
+| Black ball | At anchor |
+| Black cone (apex down) | Sailing vessel with engine |
+| Two black balls (vertical) | Not under command |
+| Ball-diamond-ball (vertical) | Restricted in ability to maneuver |
+| Black cylinder | Constrained by draft |
+| Basket | Engaged in fishing |
+| Cone (apex up) | Vessel being towed (if requested) |
+
+---
+
+## Part D — Sound and Light Signals (Rules 32–37)
+
+**Rule 32 — Definitions**
+- *Short blast* — about 1 second
+- *Prolonged blast* — 4–6 seconds
+
+**Rule 33 — Equipment**
+- ≥ 12 m: whistle + bell
+- ≥ 100 m: also gong
+
+**Rule 34 — Maneuvering and Warning Signals**
+
+| Signal | Meaning |
+|---|---|
+| 1 short | I am altering course to starboard |
+| 2 shorts | I am altering course to port |
+| 3 shorts | I am operating astern propulsion |
+| 5+ shorts (rapid) | Danger / doubt signal |
+| 1 prolonged | Vessel leaving berth |
+
+**Rule 35 — Sound Signals in Restricted Visibility**
+
+| Signal | Vessel |
+|---|---|
+| 1 prolonged (≤ 2 min) | Power-driven vessel making way |
+| 2 prolonged (≤ 2 min) | Power-driven vessel underway but stopped |
+| 1 long + 2 short (≤ 2 min) | NUC, RAM, sailing, fishing, towing |
+| 1 long + 3 short | Vessel being towed (last vessel) |
+| Rapid bell (5 sec, ≤ 1 min) | At anchor (< 100 m) |
+| Bell + gong (≤ 1 min) | At anchor (≥ 100 m) |
+| 3 strokes + rapid bell + 3 strokes | Vessel aground |
+
+**Rule 36 — Attention Signal**
+Five or more short and rapid blasts. Also a light signal of the same pattern.
+
+**Rule 37 — Distress Signals**
+Gun fired at ~1 min intervals; continuous foghorn; SOS (···−−−···); MAYDAY by voice; orange smoke; flames; parachute flare; dye; square flag + ball; high-intensity white light flashing; radio alarm signal.
+
+---
+
+## Part E — Exemptions (Rule 38)
+
+Older vessels may be exempt from some lighting requirements for a period of years after the rules came into force.
+
+---
+
+## Quick Memory Aids
+
+**Starboard right-of-way:** When another vessel is on your starboard side in a crossing situation, YOU give way.
+
+**Lights mnemonic — red over green, sailing machine:** A sailing vessel shows red (port side) and green (starboard) sidelights plus a white stern light. No masthead light while under sail alone.
+
+**The hierarchy:** NUC → RAM → Constrained → Fishing → Sail → Power
