Quiz review
All eighty original seed prompts are retained as lookup keys in
src/lib/malta-facts-patches.json; reviewed wording is applied at read time.
The database, seed scripts, lesson IDs and progress records are unchanged.
Corrections include Siculo-Arabic origins, British control versus recognition,
non-exclusive temple-age comparisons, the Order versus the republic, the
mixed legal system, spring-hunting claims, and same-sex marriage chronology.
Unsupported GDP, religion and population percentages are replaced with stable,
scoped questions. Options in each question differ by at most twelve characters
and have a maximum/minimum character ratio of 1.7. Correct positions are
balanced across the bank. The UI may shuffle the options again when playing.

Maps
Coordinates use [longitude, latitude]. Settlement and sight pins are curated
representative locations rather than entrances, legal centroids or routes.
Rabat on Malta and Victoria/Rabat on Gozo are separate targets. Mġarr Harbour
on Gozo is distinguished from Mġarr village on Malta. No administrative-region
boundaries or maritime claims are implied by these learning maps.

later coastal construction and present harbour works may differ.

The sea basin is the union of the Mediterranean and its named sub-seas,
including the Alboran, Balearic, Ligurian, Tyrrhenian, Adriatic, Ionian and
Aegean seas, Sea of Crete, Gulf of Lion, Gulf of Gabès, Gulf of Sidra and
Strait of Gibraltar. It reaches beyond Malta to Gibraltar and the Levant;
it is not cropped at the country border or opening camera.
The coarse land mask is replaced locally by Malta's finer reference coastline.
Local bay/channel envelopes are curated between coastal headlands, subtract
island land and include inner harbour branches. Offshore envelope edges are
generalised teaching limits, not physical walls. North and South Comino
channels are separate, as are Grand Harbour and Marsamxett Harbour.
Local targets take priority over the wider sea so every answer is selectable.
Artificial marine outlines are hidden and zoom-out remains enabled.

Rebuild pins, names and whole waters: python3 scripts/build-malta-map.py
The builder requires Shapely 2; production builds do not need Python.

Images
Eleven distinct local images retain Commons attribution and licence metadata
in public/images/country-guides/malta/*.source.json. The geography image is an
ESA satellite view. The language image is a distribution map. The nature
image shows Dingli village and its landscape, rather than claiming a view of
the cliff face. The fishing-boat photograph dates from 1985. The Valletta and
port photos are reference views, not a record of current construction.
Source links, creator credits and licences appear beside each image in the UI.
