* Char-mode input: deliver real keystrokes (BS/DEL, whole UTF-8, raw ESC); fix NAWS lost at logon Five input-path fixes that make raw-keystroke (get_char) applications viable, found by building the LPC TUI library on top of them: - comm.cc: char mode delivered "" for Backspace/Delete (the byte was zeroed before delivery, making BS/DEL/NUL indistinguishable). The literal byte is now delivered; line-mode in-buffer editing unchanged. - comm.cc: char mode delivered one *byte* per callback, splitting a multi-byte UTF-8 character into 2-4 invalid one-byte strings. Extraction is now UTF-8 aware: a complete sequence arrives as one callback carrying one valid character; malformed bytes still go byte-at-a-time (no stalls). - comm.cc: the "no ansi" + "strip before process input" ESC->space rewrite (both default on) also applied to char mode, so arrow keys arrived as literal "[A". The rewrite is an anti-ANSI-injection protection for line-mode commands; char mode now always passes ESC through. - net/telnet.cc: each received chunk was u8_sanitize()d independently, so a UTF-8 character split across TCP segments became U+FFFD in any input mode. An incomplete trailing sequence (new u8_incomplete_tail(), GTest-covered) is now carried over in interactive_t and prepended to the next chunk. - net/telnet.cc + comm.cc: fast clients answer the initial DO NAWS while ip->ob is still the master object, so the window_size apply fired on the wrong object and the size was lost until the next resize. The last report is cached and replayed on the user object at logon. docs/efun/interactive/get_char.md documents the delivery contract.

Everything below terminal.lpc is a pure state machine: 194 checks in single/tests/std/tui/ cover the decoder, editor sessions, history search, screen diffing and widgets headlessly. `tuidemo` / `tuidemo app` (command/tuidemo.lpc) demo both modes over any telnet client; the whole stack was verified end-to-end over a live connection including split-packet UTF-8, modifier keys, paste, resize and alternate-screen teardown.

New layers: - print.lpc — pterm-style printers that compose with plain write(): p_table (boxed, width-aware, header rule), p_tree, p_bars, p_spark, p_panel, p_bullets, p_header, p_progress, p_info/success/warn/error, and p_bigtext via the existing /std/bitmap_font. - menu.lpc + terminal glue — inline interactive prompts in the normal output flow: tui_select(), tui_multiselect() (Space toggles, list windows by height, collapses to a "? prompt: answer" line) and tui_confirm() (y/n with a default). New widgets (/std/tui/w/): table (columns + header + selection), tree (collapsible, arrows fold), checklist, radiolist, button, progress, spinner (app-driven tick()), and log (bottom-anchored scrollback pane). Showcases (command/tuidemo.lpc): `tuidemo select` (prompt chain), `tuidemo print` (all printers), `tuidemo dashboard` (animated spinner, progress bars, sparkline, live table and log on a call_out tick), and `tuidemo form` (textfield, radio group, checkboxes, buttons). Coverage: three new test files (print exact-output, menu sessions, widgets2) bring /std/tui to 8 files in the suite; the live-connection e2e run now drives all six showcases end-to-end (52 checks), including the select->multiselect->confirm chain, unattended dashboard animation, and full form entry.

Renders as a string, per-row strings, or per-cell ({ ch, attr }) pairs for blitting into a screen. - print.lpc: p_chart (multi-series braille line chart with y-axis gutter and coloured legend), p_vbars (vertical bar chart with eighth-block partial tops and optional value row), p_heatmap (2D matrix as 256-colour cells, cool-to-hot ramp, optional axis labels). - w/chart.lpc: the live line-chart widget — add_series()/add_point() rolling history sized to the widget, auto or fixed y-range; replaces the dashboard's sparkline label with a real animating graph. - `tuidemo charts` showcase; chart docs in README.md and the docs page (heatmap removed from the not-ported list). Tests: single/tests/std/tui/charts.lpc pins the braille bit math with exact glyphs, line drawing, plot endpoints, exact p_vbars output, chart/heatmap structure, and the widget's rolling window. The live e2e run verifies `tuidemo charts` output and braille frames streaming from the dashboard chart.

Registered in stdlib/index.md; README file-layout pointer updated. (Concepts' sidebar is autogenerated, so the old entry disappears with the file.)
