The Doxygen comments were generated from the declarations, so 217 @throws
lines across 21 headers read "When the corresponding validation or operation
fails" and told a caller nothing beyond the status name. The @param lines were
the same shape: every output was "Output destination populated by the
function", every instance "Object to initialize, inspect, or modify".
Rewritten against the implementations, following the pattern libakstdlib
already uses:
- @throws names the condition. akgl_sprite_load_json separated AKERR_KEY
(absent) from AKERR_TYPE (present, wrong type) from AKERR_OUTOFBOUNDS
(filename too long, or array indexed past its end), and gained AKGL_ERR_SDL
and AKGL_ERR_HEAP, which it raises and never declared.
- Parameters say whether they are required, what a NULL means, and what is
written on a failure path. Where an argument is not checked, the doc says so:
akgl_heap_next_actor's dest is a crash on NULL, not an error, and
akgl_render_2d_frame_start dereferences self before testing it.
- The conventions move up to the file blocks so the per-function docs stay
short. json_helpers.h states once that absence is an error here and that
json_t * results are borrowed; heap.h explains the pool model and the
acquire asymmetry; physics.h carries the thrust/environmental/velocity table.
- Struct fields, enum values, macros and exported globals are documented,
including the dead ones - sprite_w/sprite_h, movetimer, p_scale and
timer_gravity are read by nothing, and say so.
Also fixes ten comments in error.h and audio.h that opened with /** rather
than /**<, so Doxygen attached them to the following entity and rendered the
text as part of the macro's value. Verified against the generated HTML.
Comments only - no declaration changed. Doxygen builds clean under
WARN_AS_ERROR, scripts/reindent.sh --check passes, 19/19 suites pass.

Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.
Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.
Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.
The tree is now a fixed point of `scripts/reindent.sh --check`.
include/akgl/SDL_GameControllerDB.h is generated and excluded.

Add file, structure, global, and function documentation across all libakgl-owned headers and sources, including parameter contracts and likely AKERR/AKGL_ERR exceptions. Add a strict Doxyfile and build the generated API documentation in Gitea CI with warnings treated as failures.
