"home_intro_subtitle":"The Opening of the Year — the cosmic New Year of the ancient Egyptians",
"home_intro_p1":"<strong>Wep Ronpet</strong> — \"the Opening of the Year\" in ancient Egyptian — marked the most sacred day of the Egyptian calendar. This day corresponded to the heliacal rising of Sirius, when the star reappeared at dawn after 70 days of invisibility.",
"home_intro_p2":"The heliacal rising of Sirius is not just an astronomical phenomenon. It is a millennial meeting between humanity and the cosmos, a moment where science and spirituality meet in the light of dawn.",
"home_intro_p3":"In Guadeloupe, observing this phenomenon connects us directly to African roots, where Sirius was venerated as the herald of life and renewal.",
"feature_brightest_title":"The brightest star",
"feature_brightest_desc":"Sirius shines with a magnitude of -1.46, dominating our night sky.",

"science_mechanics_title":"The cosmic ballet",
"science_mechanics_p1":"The heliacal rising is the result of a precise celestial choreography. For about 70 days, Sirius stays invisible, hidden by the Sun's brilliance. Its return at dawn marks a unique moment when the star rises just before the Sun, visible for a few instants in the glow of morning twilight.",
"science_mechanics_p2":"Earth, in its yearly orbital motion, changes our perspective on the stars. When the Sun sits between us and Sirius, the star becomes invisible. Only when the angle becomes favourable does Sirius reappear.",

"science_diagram_earth":"Earth",
"science_diagram_sirius":"Sirius",
"science_arcus_title":"The arc of visibility",
"science_arcus_p1":"The Arcus Visionis is the critical angle: the Sun must be about 9 to 10° below the horizon for Sirius to become visible. It's a delicate balance between the star's brightness and the sky's luminosity.",
"science_arcus_p2":"For Sirius, with its exceptional magnitude of -1.46, this angle is relatively small compared to dimmer stars — which is why it is one of the first stars visible at dawn.",
"science_arcus_horizon_label":"Horizon",
"science_factor_magnitude_title":"Magnitude",
"science_factor_magnitude_desc":"Sirius shines at -1.46, making it visible even in difficult conditions. The brighter a star, the earlier it pierces the glow of dawn.",
"science_factor_latitude_title":"Latitude",
"science_factor_latitude_desc":"At 16°N in Guadeloupe, stars rise almost vertically. This tropical geometry shapes the duration of twilight and visibility.",
"science_factor_atmosphere_title":"Atmosphere",
"science_factor_atmosphere_desc":"Caribbean humidity and Saharan dust haze can delay visibility by several days. A dry, clear sky is ideal.",
"science_calc_title":"Calculating the heliacal rising of Sirius",
"science_calc_formula_label":"Main formula",
"science_calc_formula":"Heliacal rising date = Conjunction date + (Arcus Visionis / Sun's angular speed)",
"science_calc_arcus_desc":"The minimum angle between the Sun and a star for it to become visible — about 2° of altitude above the horizon for a star as bright as Sirius, reached around 50 minutes before sunrise.",
"science_calc_sources_title":"Method and sources",
"science_calc_sources_text":"Per-site dates are interpolated from Jean Meeus's tables (arc of vision as a function of latitude) and cross-checked against astronomer Jeffrey L. Hunt's calculations (whenthecurveslineup.com). At 16°N, interpolating between 10°N (July 17) and 20°N (July 24) gives a heliacal rising around July 22-23 — consistent with traditional observation in Guadeloupe. The actual observed date still depends on weather and the clarity of the eastern horizon.",
"culture_title":"Culture & Knowledge",
"culture_subtitle":"A millennial heritage uniting Africa and the Caribbean",
"culture_egypt_title":"Egypt: Sothis, goddess of the Nile",
"culture_egypt_desc":"For the ancient Egyptians, the heliacal rising of Sirius (Sothis) was the most important event of the year. It announced the flooding of the Nile, a source of life and fertility. This \"return\" of the star marked the New Year and symbolised rebirth, associated with the goddess Isis.",
"culture_dogon_title":"Dogon: keepers of stellar knowledge",
"culture_dogon_desc":"The Dogon people of Mali hold astonishing knowledge about Sirius. They knew of the existence of Sirius B, a white dwarf invisible to the naked eye, long before its scientific discovery. Their 60-year ritual cycle, the Sigui, is directly linked to their understanding of the Sirius system.",
"culture_caribbean_desc":"In the Caribbean, Sirius has guided sailors for centuries. Indigenous peoples and African mariners used its rising to mark the seasons and navigate between islands. Even today it remains a fundamental landmark for traditional fishermen.",

"dogon_cosmogony_p2":"The Sigui, celebrated every 60 years, marks the renewal of the world and commemorates the revelation of speech to humankind. This roughly 60-year period is close to Sirius B's 50-year orbit around Sirius A, adjusted by ritual considerations.",
