The moves that should be in bold are on the right of the solutions (below).

Example 1
a) 1.Sd5 Tf1 2.Td8 Df7 # in bold: 1.Sd5
b) 1.Ld3 Te1 2.Dd7 Dxg8 # in bold: 1.Ld2
c) 1.Ld4 Tb1 2.0-0-0 Db7 # in bold: 1.Ld4

Example 2
a) 1.Sc3 Lc5 2.Kc4 Se3 # in bold: 1.Sc2
b) 1.Se3 Tc5 2.Kd4 c3 # in bold: 1.Se2

Example 3
1.Se2 Sf6 2.Tb5 S:e2 # in bold: 1.Se2
1.Sc7 Sf5 2.D:c3 S:c7 # in bold: 1.Sc7

use "[ b ]" (without spaces) to start bold, and "[ / b ]" (without spaces) to end bold.

Thus, "a) [ b ] 1.Sd5 [ / b ] Tf1 2.Td8 Df7 #" (without spaces) comes out as follows...

Example 1
a) 1.Sd5 Tf1 2.Td8 Df7 #
b) 1.Ld3 Te1 2.Dd7 Dxg8 #
c) 1.Ld4 Tb1 2.0-0-0 Db7 #

Example 2: here, the moves you give, which should be bold, do not correspond to any moves in the solution.
a) 1.Sc3 Lc5 2.Kc4 Se3 # in bold: 1.Sc2 ??
b) 1.Se3 Tc5 2.Kd4 c3 # in bold: 1.Se2 ??

Example 3
1.Se2 Sf6 2.Tb5 S:e2 #
1.Sc7 Sf5 2.D:c3 S:c7 #

Example 2
a) 1.Sc3 Lc5 2.Kc4 Se3 #
b) 1.Se3 Tc5 2.Kd4 c3 #

Example 3

In example 3, the moves 1.Se2 and !.Sc7 are given as thematic. I am not so sure.

The sacrifice and setting up of the white battery are immediately apparent after those moves. Is it only partially apparent? Perhaps the time delay in firing the battery makes them thematic.
