# Effects: feel reviews

Each effect of docs/render-pipeline.md §9 lands behind its own switch, off,
and is kept only after a feel review (§8.4): a frame series on the virtual
clock, a recording, and a verdict — keep, polish or drop — with one line of
why. The verdict is the user's.

| effect | switch | state | review material | verdict |
|---|---|---|---|---|
| Crt (bundled post pass) | `Crt 0..3` | kept, rewritten (no barrel) | fx-compare stills, live window | kept at the user's live look |
| Ripple, Glitch | — | removed | live window | dropped by the user after a live look |
| G1 soft elevation shadows | `Lift` (off) | opt-in until the focus-lift default is decided | frame series + mp4 per theme (forge, acme, dusk): Lift on, a focus switch, a run of quick switches, a notice, Lift off | pending |

Notes on G1: the lift runs on a critically damped spring (§7.2) that settles
in about 240 ms and keeps its velocity when a quick run of switches retargets
it; a notice floats on a lift of 1 while Lift is on. The series are the core's
frames: core animation steps at 62.5 Hz on any display (§7.1), so a 144 Hz
display shows the same frames, each held for two or three refreshes.
