The engine already auto-ticks SpriteAnim/Motion; it now auto-DRAWS too.
Declare a Sprite component (id/offx/offy/scale/flip/tint/hidden, shipped from
ludic.core) on an entity with a Position and esys_sprite draws it each Render
frame — no hand-written Render handler, no hand animation (adds the SpriteAnim
frame when present). Registered on the engine-system registry (Render) and
spliced only when the game declares Sprite, so a game that never declares it
compiles byte-identically; opt out by omitting Sprite or `disable system
esys_sprite`.
Deprecates the bare draw_sprite/draw_sprite_scaled globals in favour of
Screen.sprite/Screen.sprite_scaled: a direct bare call emits a one-time
compile-time deprecation note (the bare form still lowers, since Screen.sprite
uses it); migrates the chronorift demo to the namespaced calls (golden render
byte-identical).
Example sprite_render (pixel-readback: engine draws the sprite, respects
hidden). Full suite 109/0, goldens byte-identical, fixpoint holds.

The engine-owned esys_move (#65) reads Position/Body/Collider/Solids by name,
but no package defined them — every game and example re-declared identical
bundles by hand. Ship them as the source package ludic.core; games import
instead of copy-pasting, and extend by composition (attach their own
components on the same model). AOT → compiles into the consumer's ECS with no
seam; integer + Q16.16 deterministic. Adds examples/library/core_components
(driven by esys_move, composed with a game Health component) as a
controller_case (104/0).

docs/CONTROLLERS.md documents the mechanism-vs-policy thesis, the six extension
levers, the ludic.gameplay/platformer/shooter/npcai/rpg packages, and how to
build a game against them.
