small css fixes, and replaced filler text with description

IM DONE WITH ANIMATIONSSSS

made satellite mode

UGH OKIE
WE HAVE SMTHING
tHIS WAS SM EASIER THAN NBODY

wrote index.html
fixed font issues in nbody.html
ig did smthing on the css
will update later

will write this properly. I promise. rn I need to lock innn

kinda in flow state so will update later alr???

• Euler was causing energy drift so added replaced with fixed step RK4.
• getDerivs() temporarily overwrites positions so accel() can be evaluated at intermediate stages, then it restores them. (this took me so long to figure out… the bodies were teleporting because I forgot to restore.)
• you couldnt see outer planets before, so I added cursor anchored zoom and pan
  ‎‎
  so now…, you can see all the planets (and bodies in the future) cuz I added zoom and pan.
  orbits are now stable long term!!

  TODO:
• add gravitational softening
• add new bodies on click
• add trails behind bodies

WE NOW HAVE 5 BODIES!!! AND THEY MOSTLY OBEY THE LAWS OF PHYSICS!!
‎

• added Sun, Mercury, Venus, Mars and Earth.
• labeled bodies
• gravity calculated b.w every pair of bodies
• set G = 4π², stable orbits.
• added integration using Euler method, so velocity and position update by (dt).
• real time to sim. time scaling (1 sec = 0.05yrs in sim. time)
• background changes (stars)
• sim. time in corner
  ‎
  basically we got more planets, stable orbits, with gravity working for multiple bodies anddd speeds look realistic relative to each planet.
  ‎
  TODO:
• SWITCH TO BETTER INTEGRATION METHOD FOR ENERGY STABILITY (RK4??)
• add trails behind bodies (so basically orbital trails)
• update and add back the navbar that I removed in this version
  ‎
  ramblings..
  I have a rough idea on how to add the bodies (like the user adds the bodies… the acutal point of this sim) , at least the research is done. ive also kinda figured out how to implement binary stars so… idk. anyway lot left to do but in theory, at least, I know what to do!!

set up canvas and render loop now works!!
then added two bodies:

• sun in the middle
• small blue body orbiting it with sideways velocity.

• added duty cycling so once duties are added once they auto-cycle every month (took very long to figure out!! bugs everywhere!!)
• you can now change the colours, fixed the really bad tailwind config (these ones look trash)
• ready to shippp!!!

• made minor css changes to fix colour palette (changed black text to white)
• (bug fix) updated models.py for the duty_roster model so as to not show overdue duties anymore
• shifted from css to tailwind
• added code verification for password change and email notifications for meetings, duty timings, new announcements.
• fixed css for dark mode
