 * This guarantee is load-bearing, not cosmetic: the renderer repaints by moving
 * the cursor up N lines, so a frame taller than the viewport scrolls its own
 * top off screen and every repaint appends a copy instead of overwriting. Four
 * progressively stronger reductions are tried, and the result is clamped.
 *
 * `minTier` exists so a caller that repaints repeatedly can pin the tier once
 * it has had to compress: an active step's own detail (its progress bar, its
 * task list) and a `"bottom"`-placed log tail both change height every tick on
 * their own, with nothing about *other*, already-finished phases changing at
 * all. Re-deciding "does everything fit?" from scratch on every frame means
 * that harmless wobble alone repeatedly drags the whole body across the fit
 * threshold — every finished phase flips between full and one-line collapsed
 * along with it, which reads as the frame randomly changing its mind rather
 * than reacting to anything the user did. Once a tier has been needed, holding
 * it keeps already-settled phases settled even while the active step's own
 * footprint keeps moving.
