Website: machine estimator v3.1 — bar never below an 8 GB box; a single leftover app keeps its name (R-997)

Empty or tiny selections drew a ~2.3 GB box whose base system (1,636 MB) no real box
has; the bar is now floored at the smallest named size (8 GB) for its parts only — the
recommendation and the rule are unchanged. Grouping applies only to two or more
leftover apps; a ninth app is shown by name in the group's colour. Tests: 12, the
new ones red-proofed.

+## 2026-10-13 (night) — estimator v3.1 tests
+
+- `test_build_sizing_web.py` (12 tests): the bar is never below the smallest named box, its parts still sum to it
+  within 1 MB (nothing ticked, one tiny app, household, all 62), the base system never below the 8 GB split (4,096);
+  9 apps → 9 named parts, 10 apps → 8 named + a group of 2. Red-proofed: the floor removed from the JS and from the
+  mirror, and grouping a single app in the JS and in the mirror, each convicted.

 ## 2026-10-13 (evening) — estimator v3: segments and the English article under test
 
 - `build_sizing_web.py`: `bar_app_colours` (8) in the data file, so the script holds no number of its own.

+- **The bar is never drawn for a box smaller than 8 GB** (the smallest size the page names). With nothing or very
+  little ticked, the „fits well" size was about 2.3 GB, where the installer's ceiling clause gave a 1.6 GB base

+  empty-selection sentence uses the same split. The recommendation and the rule are unchanged.
+- **No more „további 1 alkalmazás".** The smallest apps are grouped only when two or more are left over; with exactly
+  nine apps the ninth keeps its name, in the group's neutral colour (no ninth palette colour).
