Clearer market prices and upwind warnings

The Prices page now shows both what you pay to buy and what you receive when selling. World-price comparisons use one shared benchmark and include your actual duties and trading privileges, so the two sides can be compared fairly.

Trading and privateering

• Added Buy and Sell columns, each with its own world-price comparison. A dash means the port does not currently offer that good for purchase.
• Both price columns can be sorted. Narrow windows stack the figures without shrinking the pixel fonts.
• Fixed small price differences being described as exactly the world price. Bulk trades still reflect changing supply and demand and whole-doubloon rounding; their quoted totals match the transaction.
• Hailing and attack confirmation now explain when none of your letters of marque covers the target. A letter covers wartime enemies, not every unfriendly nation.
• A lawful attack no longer becomes piracy retroactively if peace is signed before the enemy surrenders. A new attack still checks current authority.

Wind and accessibility

• The wind V pulses coral in both standard and colourblind modes. After sustained sailing directly into the wind, it gently moves outward and back, then displays a small localized Upwind label. Turning out of irons clears it.
• The stronger warning stays quiet on ships with oars and wherever shore hauling is available. Reduced-motion preferences keep the cue still.
• Added a colourblind-friendly option with alternative interface inks, ship outlines, reserve bars and redundant danger markers. National flags retain their colours. The preference persists between voyages.

Text and reliability

• Fixed localization gaps in colonial defense dialogue, canoe result notices and animal encounters, including declining a companion.
• Fixed a treasure-island waypoint being misread as an internal map category.
• Fixed commission reward details using English number separators in other languages, expanded inventory categories displaying internal text, and a clipped French controls caption.
• Improved blocked-turn diagnostics to retain the attempted heading and the obstructing bank before collision rollback.

These changes apply to the full game and demo.
