feat: 3 interactive demo pages + transforms/sieve/linear engines
...
Lessons:
- /hinh-hoc/dinh-ly-pythagoras (lớp 7) — drag right-angle vertex; "Chứng minh"
button plays Euclid-style dissection-shear animation tweening two leg-squares
into the hypotenuse-square. Respects prefers-reduced-motion.
- /so-hoc/sang-eratosthenes (lớp 6) — 10×10 grid; click 2/3/5/7 → ripple
cross-out of multiples in 4 colors; roving tabindex; aria-live announces.
- /dai-so/duong-thang (lớp 7) — y = ax + b plot; 2 sliders + 2 draggable
anchors bidirectionally bound via draggable.onChange + viewport clamping +
rounded epsilon gate (no oscillation at any drag speed).
Engines:
- geom-engine/transforms.js — translate, rotate, shear, compose, applyToPolygon (13 tests)
- numtheory-engine/sieve.js — sieveUpTo, multiplesOf, isPrime (10 tests)
- algebra-engine/linear.js — lineFromPoints, yAt, linePoints (6 tests); new module bootstrapped
Glue:
- registry: insert 3 new lessons in topic+grade order
- tailwind: extend colors.pair to 4 entries (pair.4 = #5E60CE for prime 7)
- README: bump count 5→8, list new URLs, update architecture section
