Clay doesn't account for border widths in layout — borders were drawn as visual overlays, so any element with border width > padding had its content collapsed behind the border glyphs (or, for fit-height boxes, collapsed to a single row with top and bottom glyphs overlapping and children invisible). Fix: at pack time, compute effective padding per side as max(userPadding, borderWidth). Border glyphs draw in the same cells as before; only the Clay layout values change so the engine reserves those cells. Semantics of the max rule: - No explicit padding: border width becomes the effective padding; content lands inside the border, not behind it. - padding == borderWidth (prior workaround): max evaluates to the same value, no double-reservation; these elements render identically. - padding > borderWidth: extra padding provides breathing room inside the border, measured from the border edge inward. Callers who set padding == borderWidth as a workaround are unaffected. Downstream compensators (e.g. lgtm.shop Panel) will render identically until they drop the manual compensation on their next pin bump. Resolves Open Decision #4 in specs/renderer-spec.md.

Border presence implies padding on that side equal to the border width. Callers who compensated by setting `padding == borderWidth` now receive double-reservation and must remove the workaround padding. `padding: 1` with `border: 1` → effective 2; `border: 1` alone → effective 1.

previously, bordered elements collapsed when no padding was set. Clay treats borders as visual overlays and does not account for them in layout, so text in the terminal was rendered behind the border glyph
now, tty intercepts borders at
pack()time and passes an effective padding to Clay that equalsuserPadding + borderWidthper sidebreaking change: border presence now implies a minimum padding equal to the border width. callers who compensated by setting
padding == borderWidthnow get double-reservation and should remove the workaround padding!
