* improvement(emcn): normalize the chevron geometry and consolidate consumers The sidebar folder arrow read as much larger than the icons beside it. It was measurably so: `ChevronRight` was a triple outlier in the icon set. | | ChevronRight | house standard | |---|---|---| | viewBox | `0 0 6 10` | 24-based — 149 of 173 icons | | glyph fill | 80% of the box | 54% median | | strokeWidth | 1.2 | 1.55 — 153 of 173 | | cap/join | square/miter | round/round — 175/177 | Because the box was tight-cropped, a square `size-[16px]` scaled the glyph to 12.8px tall where a standard icon shows ~8.6px — about 50% larger, with a relatively ~85% heavier stroke. The lucide icon it replaced was a 24-box at 50% fill, which is why this only appeared after the migration. `chevron-down`, `chevron-right` and `chevron-left` are rebuilt as the exact mirror and transpose of `chevron-up`, which already sets the house standard, so their optical weight is identical to that sibling by construction rather than by eye. Changing the viewBox is not safe on its own: 36 call sites sized these to the old tight aspect (`h-[7px] w-[9px]`, `h-[6px] w-[10px]`, ...), which would letterbox against a square box. All of them move to `size-[14px]`, the documented default and the app's dominant size (212 uses). Every one of the 94 chevron call sites is now square-sized. Two of those were only reachable through indirection and would have regressed silently: `STYLES.chevron` in the terminal's structured output, and the sidebar-section chevron inside a multi-line `cn()`. The dropdown submenu chevron carried no size at all and was relying on the icon's intrinsic 6x10 — it would have jumped to 24x24. Also unifies `folder-input`, which carried both 1.55 and 2 within one icon. Docs consolidation, same theme — it was forking shared components: - `SidebarChevron` was a private inline copy of the old 6x10 chevron; it now wraps the shared `ChevronRight`. - `ThemeToggle` inlined lucide's sun and moon at strokeWidth 1.5; both now come from `@sim/emcn/icons` at the house 1.55. Docs inline `<svg>` files drop from 9 to 7; the remainder are the brand icon set, the logo, OG-image generation and bespoke hand-positioned shapes. Left alone: 16 icons whose stroke or box still differs. They are fill-based glyphs and brand marks (`sim`, `wordmark`, `folder`, `more-horizontal`, ...) where changing the stroke means redrawing the icon — that wants visual review, not a sweep. Verified: 23/23 type-check (--force), biome, api-validation, 18361 tests, and production builds of both apps. * docs(emcn): correct the chevron geometry left in two comments ChipChevronDown's TSDoc still described centring a 10x6 glyph, and the enterprise sidebar's chip-parity comment still cited a 6x10 chevron. Both now read 14px, matching what the components actually render.
