The remaining lighting tiers from the original proposal, all extending the deterministic accumulation core (light.ludic) — no new ECS plumbing: - Light.spot: cone / flashlight lights (direction + spread degrees), with a self-contained integer atan2-in-degrees and a feathered edge. - Light.falloff: a brightness-ramp exponent (1 linear, 2 quadratic, …) via repeated fixed multiply. - Light.soft: soft shadows — an area-sampled light so an occluder edge fades through a penumbra instead of a hard cut. - Light.gel + Light.clear_gel: colour cookies — a light gels from its centre colour to a rim colour. - Light.normal + Light.clear_normals + Light.height: a normal G-buffer so surfaces shade by facing (N·L), not distance alone (tier 3). - Light.time_of_day: a day/night ambient ramp from a single 0..1 value. The engine lighting system (systems_light.ludic) consumes matching optional Light2D fields — direction/spread/falloff/softness/gel — each defaulting off so an older five-field Light2D lights exactly as before. Every tier is integer + Q16.16 fixed, so scenes light identically on every run and headless. Worked example + regression: examples/library/light_tiers.ludic (1 1 1 1 1 1 1 1 1). Nine new docs/language/light pages. Full suite 76 passed, self-host C-free fixpoint intact, no golden drift. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

Changesets
A changeset is one small Markdown file describing a single user-facing change,
dropped in this directory. x release consumes every changeset here into a new
CHANGELOG.md section, bumps VERSION, and deletes the consumed files.
Format
bump: minor
type: feat
One or more lines describing the change, in the past-agnostic imperative used in
the changelog. Markdown is fine.
bump:—major,minor, orpatch(SemVer). The release version is bumped by the highest level among the pending changesets (unlessx release <level>overrides it).type:— the Conventional Commit type (feat,fix,perf,docs, …); it becomes the bold prefix of the changelog bullet.
Adding one
Create a file with a short, unique name, e.g. changes/regex-namespace.md. Any
filename works except this README.md, which the release step always skips.
